Description

Calming your office cacophony with soundproofing requires a team effort.  Acoustical consultants assess noise levels and recommend solutions. Architects design soundproof elements to renovate. Contractors install soundproofing materials like walls, doors, and baffles. Working together, these pros create a quieter, more productive workspace.

Noise in the office can be a serious problem, interfering with employee concentration and reducing work efficiency. Therefore, office soundproofing is an integral part of creating a favorable working environment.

Its main goal is to reduce noise generated by both external sources (passing cars, construction activities) and internal ones (employees talking, equipment noise), which helps to increase productivity and reduce stress levels.

Office noise is one of the most common complaints from employees working in corporate offices. Especially in open space offices where employees are housed together in one open space. High noise levels in the office can be a serious problem affecting concentration and productivity.

Although there is no such thing as a completely silent office, an important task for the employer or designer planning an office interior is to soundproof the office to reduce the overall background noise that affects the comfort of the work environment.

How important is office soundproofing?

As is well known, the fundamental elements of sound are the frequency of variation of sound waves and their intensity. Frequency is expressed in hertz (Hz), that is, in vibrations per second (the human ear distinguishes noises with frequencies varying from 20 to 20,000 Hz, with the point of greatest sensitivity reached at around 3,000 Hz). Regarding intensity, one of the most common measurement systems is the representation on a special scale of the noise pressure level expressed in decibels (dB).

It has been scientifically proven that the human body experiences a sensation of discomfort at an average value of 50 dB. When levels close to 90 dB are reached, a sensation of pain occurs. The threshold for physical pain is 130-140 dB. From this data, it is easy to deduce the importance of soundproofing in offices.

Office soundproofing creates a more controlled and acoustically balanced work environment. We achieve this through two main approaches:

Sound blocking and absorption

Office soundproofing involves blocking and absorbing unwanted noise to minimize disruptions and improve focus for employees. Soundproofing helps with containing confidential conversations within specific spaces and preventing them from bleeding into other areas. This can be particularly important for open-plan offices.

By achieving these aims, office soundproofing offers several benefits like increased productivity, improved employee satisfaction, and a more professional work atmosphere.

There are several problems related to soundproofing and acoustics in office premises. One of them is insufficient sound absorption in the room. This can lead to echoes and reflections of sound from the walls and ceiling, which impairs speech understanding and creates a noisy environment.

Another problem is the unwanted background noise created by various noise sources in the office. Employees talking, phones ringing, equipment noise – all this can distract and interfere with concentration.

Of all the interior solutions, acoustic partitions cope best with this task. The special design and materials of the partitions create a sound absorption effect. And, the abundance of different shapes and fastenings is suitable for a transformation of the working environment.

Partitions can be:

• stationary or mobile;
• floor;
• hanging;
• desktop.

Table partitions

Table partitions can be a simple yet effective way to reduce noise levels and improve privacy in an office setting. These partitions can be placed on top of desks or tables to create a physical barrier between workstations.

When choosing table partitions, consider materials that are both sound-absorbing and durable. Options include acoustic panels, fabric-covered partitions, or even simple cardboard dividers. The thickness and height of the partition will also impact its soundproofing effectiveness.

For maximum benefit, ensure that the partitions fit snugly against the table and are properly secured. You may also want to consider adding sound-absorbing materials to the underside of the partitions to further reduce noise transmission.

Hanging screens

Hanging screens offer a flexible and aesthetically pleasing way to enhance soundproofing in office environments. These screens can be easily moved or adjusted to accommodate changing layout needs, making them a popular choice for open-plan offices or areas with frequent noise fluctuations.

Typically made from materials such as fabric, acoustic panels, or a combination of both, hanging screens can be customized to match your office’s decor. They can be used to create private workstations, divide conference rooms, or simply reduce ambient noise levels. By strategically placing hanging screens, you can significantly improve the acoustic quality of your office, leading to increased productivity and employee satisfaction.

Floor partitions

In the bustling world of modern offices, noise pollution can significantly hinder productivity and employee satisfaction. One effective solution to this problem lies in the strategic use of floor partitions. These partitions, when designed and installed correctly, can significantly reduce noise transmission between different areas, creating a more peaceful and focused working environment.

By incorporating sound-absorbing materials like acoustic panels or fabric-covered partitions, offices can effectively dampen unwanted noise. These partitions not only serve as physical barriers but also act as sound-absorbing barriers, preventing noise from traveling to adjacent spaces. Additionally, the height and thickness of these partitions play crucial roles in their effectiveness. A well-placed partition can provide a much-needed respite from the constant hum of office activity.

Permissible noise level in the office

To ensure a comfortable working environment in the office, there are certain standards and acceptable noise levels. In Kenya, as in many other countries, sanitary rules and regulations are applied that regulate the noise level in office premises. Usually, the acceptable noise level in the office is about 50 dBA during the day and 30-40 dBA at night.

Noise measurements in office premises are carried out with the sound level meter microphone positioned at the height of a seated person’s ear.

The order and stages of  office soundproofing

Office soundproofing includes several stages. The first step is to conduct an acoustic assessment of the premises to identify key noise sources and the most problematic areas.

Next, the necessary materials are selected and installed, such as soundproofing partitions and sound absorbers. It may also be necessary to use special soundproofing finishes for walls, ceilings, and floors.

An important stage is testing and adjusting the soundproofing system to achieve the best results. Upon completion of the installation, a control inspection and verification of the effectiveness of the soundproofing is carried out.

The main sources of noise in the office and how to eliminate them

Let’s take a closer look at the reasons for increased noise in the office:

1. Noise from adjacent rooms due to insufficient insulating capacity of separating structures;
2. Then, noise emitted by equipment or communications located directly in the room;
3. Noise emitted by equipment located at a significant distance from measurement control points;
4. high noise levels from various sources on the street (highways, railway transport, etc.), creating a constant elevated background noise.

Adjacent premises

When installing dividing walls inside an office space, you rarely think about your soundproofing. The fastest and cheapest option involves installing a single suspended ceiling over a large area and then installing dividing partitions. In such a case, the main obstacle to the spread of noise is only the suspended ceiling slab, whose insulating capacity is extremely low. Also, the cause of extraneous sounds can be the low intrinsic insulation coefficient of the existing barrier made of inexpensive materials and the presence of acoustic gaps in the form of sockets, switches, niches, etc.

To determine the methods of combating the listed problems, it is enough to visually inspect and listen to the integrity of the partition using simple equipment, with the source in the neighboring room turned on. The solution can be implemented within a few days from the moment of contacting Wallpaper Kenya.

Equipment and communications

Air ducts, freon pipes, water pipes, and other communications and equipment located in proximity to workplaces can also be the cause of discomfort. Here, individual solutions based on measurements obtained with a noise meter may be needed. You can read more about the methods of insulating communications in this article.

Soundproofing of air ducts in the office

Equipment at a distance

Noise transmission from equipment located at a considerable distance can occur both by air and by structure through existing rigid contacts. The fight against noisy equipment that transmits sound through the air and involves building structures in the oscillatory process, which in turn emit sound into the air, requires an individual approach based on calculations.

Street noise

The reason for penetrating noise from the street, characterized by a constant high background, in the form of a highway, construction site, and railways, can be windows with low sound insulation. When choosing translucent structures, it is necessary to pay due attention not only to information about the sound insulation of the window but also to their proper installation.

Only when creating conditions in which the frame abutment nodes will have a noise insulation level not lower than the noise insulation of the window itself, can we talk about the feasibility of their installation.

Standard installation using foam leaves a significant space for unwanted sounds to penetrate and significantly worsens the overall efficiency of the entire window structure. The solution to the problem is quite simple and does not entail a long execution time and large financial costs.

Sound Absorption in offices

Acoustic Panels

Acoustic panels are superstars in office soundproofing. Made from sound-absorbing materials, they soak up noise waves like a sponge. This reduces echo, reverberation, and overall noise levels, making the office quieter and calmer.

Imagine a conversation at one desk not booming across the entire workspace. Acoustic panels, placed strategically on walls or ceilings, can make that a reality. This translates to better focus, less distraction, and improved privacy for confidential discussions. They even come in various styles, so you can boost acoustics without sacrificing aesthetics.

Upholstery and carpets

Carpets and upholstery act as sound warriors in your office! Unlike hard surfaces that bounce noise around, these soft heroes absorb sound waves. This reduces echoes and creates a quieter environment.  Think plush carpets with thick padding and comfy upholstered chairs. They not only dampen noise but also provide a more comfortable workspace.

Bonus: strategically placed furniture upholstered with sound-absorbing fabrics can create sound barriers within open offices.

Plants can help dampen noise

Believe it or not, plants can help dampen noise! They provide a natural sound-absorbing barrier. Indoor plants can be your leafy allies in the battle against office noise.

Because plants have leaves, stems, and soil that work together to absorb sound waves. The more foliage a plant has, the better the absorption.

By breaking up hard surfaces and sound waves, plants help prevent echoes that bounce around the room.

While plants won’t silence the office entirely, they can create a noticeably calmer and more focused environment.

Sound Blocking in offices

Sound blocking aims to create physical barriers to noise. Therefore solid core doors and higher cubicle walls act like fortresses, containing conversations and keeping outside noise at bay. Think of them as sound stoppers, not just sound absorbers. This is ideal for open offices or areas requiring extra privacy.

Wall Partitions for office soundproofing

Office walls can be your first line of defense against noise!  Sound-blocking wall partitions are like noise-canceling headphones for your workspace. These partitions, often made of dense materials like drywall or soundproof panels, create physical barriers that stop sound waves from traveling between areas. Taller cubicle walls or separate offices with soundproofed walls are ideal solutions. This approach is especially effective for blocking out loud conversations, phone calls, or noisy machinery, promoting a quieter and more focused work environment.

Soundproof  office doors

Solid core doors with good seals will block sound from entering or exiting a room.

Slam the door on noise distractions! Soundproof doors are like bouncers for your office. They feature solid cores, thick seals, and sometimes even special finishes to block sound from entering or escaping a room.

This is perfect for conference rooms, private offices, or any space needing extra noise control. They keep confidential conversations in and disruptive sounds out, promoting a more peaceful and productive work environment.

Acoustic baffles

Banish echoes and background noise with acoustic baffles! These are sound-absorbing panels that hang from the ceiling in open offices.  Imagine them as noise ninjas, silently absorbing sound waves and reducing overall noise levels. This helps control echoes and reverberation, creating a calmer and more focused work environment for everyone.

Other Strategies

Designated Quiet Areas

Your office can be a productivity oasis with designated quiet areas! These are specific zones for focused work, with minimal traffic and noise sources. Think windowless nooks with comfy chairs, or partitioned-off sections with “shhh” signage.  This allows employees seeking concentration a haven to tackle demanding tasks without distractions.

Sound Masking Systems

Ever feel like office chatter is drowning out your focus? Sound masking systems come to the rescue! These emit a low-level, unobtrusive background noise that acts like a sonic camouflage.  This subtle sound masks distracting conversations and background noises, creating a calmer and more acoustically balanced work environment. Think of it as a white noise machine for your office, promoting better concentration and productivity.

Furniture Layout as sound barriers

Think of furniture as building blocks for better acoustics!  Strategically placed furniture can act as sound barriers and create quieter zones within an office.  Position bookshelves or tall cabinets along shared walls to absorb noise from neighboring areas.  Upholstered furniture like couches or armchairs can also be used to create sound barriers, separating noisy areas from quieter ones. This clever layout helps manage sound flow, promoting a more focused and conversation-controlled work environment

Benefits of office soundproofing

Increased productivity

Improving acoustic comfort in the office directly affects work efficiency. Employees in low-noise environments demonstrate better concentration and are less prone to distraction, which contributes to increased overall productivity.

Maintaining the health of employees

Constant noise can lead to hearing loss, hypertension, and even cardiovascular problems. You can help maintain the health of employees with soundproofing.

Improving privacy

Protecting confidential information is a critical aspect of the work of many companies. Soundproofing of premises provides the necessary level of sound absorption to prevent leakage of important information.

Comfort and company image

Attract and retain new employees with a comfortable working environment. The image of a company that cares about the comfort of its employees grows in the eyes of customers and partners.

Important Note

Soundproofing isn’t always necessary. Sometimes, sound absorption is the key.  Consider what your specific needs are before diving into major renovations.

Don’t rush into a soundproof fortress! While blocking noise has its place, sound absorption can be a quieter hero. This approach tackles echoes and reverberation, creating a calmer environment without blocking sound entirely.  Think soft carpets, upholstered furniture, and even leafy plants.  Consider your needs: is privacy key, or do you just want to tame the noise? The right solution can boost productivity without a major overhaul.
