The importance of acoustics in interior design is often overlooked—until noise starts affecting productivity. Imagine trying to focus on an important task while surrounded by conversations, ringing phones, and constant background noise. In many modern offices, especially open-plan layouts, this is a daily challenge.

Understanding the importance of acoustics in interior design helps businesses create environments that support concentration, collaboration, and employee well-being. Without proper acoustic planning, even the most visually appealing workspace can become inefficient and stressful.

Why the Importance of Acoustics in Interior Design Matters?

The importance of acoustics in interior design goes beyond comfort—it directly impacts how people work and feel in a space.

  • Reduces distractions and improves focus
  • Supports clear communication and collaboration
  • Enhances employee well-being
  • Creates a more professional and functional environment

Modern offices must balance aesthetics with sound control to achieve optimal performance.

The Role of Acoustics in Modern Interior Design

Recognising the importance of acoustics in interior design is essential as workplaces evolve. Open-plan offices encourage collaboration, but they also allow sound to travel freely, increasing noise levels.

Glass walls, high ceilings, and hard surfaces—common in contemporary design—can amplify sound rather than absorb it. This makes acoustic planning a critical part of interior design rather than an afterthought.

Designers now integrate acoustic solutions early in the planning stage to ensure spaces are both visually appealing and acoustically balanced.

Types of Noise in Workplace Interior Design

To fully understand the importance of acoustics in interior design, it’s important to identify common workplace noise types:

Continuous Noise

Continuous noise is any unpleasant sound constantly playing, such as factory equipment or engine noises. It can come from heating and ventilation systems or printers in office buildings. Traffic noises from outside are also classified in this category.

Intermittent Noise

Intermittent noise goes from quiet to loud and back in short intervals. Some instances include trains passing by, planes flying overhead or factory equipment operating in cycles.

Impulsive Noise

Impulsive noises burst out suddenly, leaving you startled. These can result from sudden laughter or applause from co-workers inside the workspace and construction or demolition work outside.

Low-frequency Noise

As the name suggests, low-frequency noise includes low rumbles and hums. We hear such noises from appliances like refrigerators or nearby power stations.

These noises that impact your business can be internal (from within the workplace) or external (from outside). No matter the source, it’s crucial to reduce the impact, and there are various ways to do so. Read on to find out.

Benefits of Acoustics in Interior Design

No matter how aesthetically pleasing your workplace ambience is, if it doesn’t accommodate sound adequately, it’s not worth it. Long-term exposure to noise in an office environment is detrimental to your business. A modern workplace with just the right amount of sound circulating throughout the space is vital in terms of productivity, privacy, and employees’ well-being. Let’s explore each one.

1. Boosts Productivity

Research conducted by ABC News in a simulated open-plan office shows a causal relationship between open-plan office noise and physiological stress. According to the study, office noise escalates negative mood by 25%. This negative impact on mood directly affects the ability to perform well at work.

Proper acoustics can make all the difference in an office setting. With reduced background noise, employees can focus on their daily tasks without distractions from other areas of work or personal conversations spilling on them constantly.

2. Enhances Employee Wellness

In a 2019 survey regarding noise and well-being at work, we find a staggering number of office workers who said that noise at their job impacts how well they work. Over 65% of workers struggled to complete work accurately and timely, with 44% noting a negative impact on stress levels and overall wellness.

For many, intense noise is the most common trigger that causes physiological stress responses. These include spikes in blood pressure or increased heart rate, to name a few. Apart from stress, other possible health effects include high blood pressure, weight loss, sleep disruption, and hearing loss, which can lead someone down an unhealthy path towards depression.

Acoustic solutions are an ideal way to help organisations achieve the right balance of sound for a collaborative workplace, boosting employees’ physical and mental well-being.

3. Provides Privacy

The acoustic needs of the modern office are more demanding than ever. No matter how communicative your space is, not everyone in your workspace needs to know what you’re doing. There must always be a private meeting or sensitive conversation area that neither reverberates sound outside nor inside in an open plan environment.

The acoustic workplace design incorporates designated spaces to take care of private matters or uses acoustic treatments like sound absorbents in offices to ensure employee privacy, making them feel safe.

How Much is the Perfect Amount of Sound?

When thinking of an acoustic workspace, you might envision a quiet place. However, like a loud workspace, extreme silence also makes a workplace acoustically unpleasant.

When there’s pin-drop silence, you can even distinctly hear hushed conversations or sounds of pop-up notification from across the room, which isn’t ideal for an acoustic workspace. It’s necessary to have some level of sound but if it’s too loud, you can opt for sound control techniques.

It’s recommended that an office setting with large open spaces have a sound of not more than 70 dB. The sound of people talking or machinery beeping in the background should be 45-55 dB to maintain an optimal acoustic environment and ensure health and happiness.

Now that we understand the importance of acoustics in modern workspaces and the optimal sound to achieve a healthy workspace, let’s find out how to reduce noise in an open-plan office.

The ABC of Noise Control in Modern Workspaces

There are many measures to control workplace noise. The ‘ABC’ of acoustics refers to absorption, blocking and covering. You can use one or all of them depending on your requirement.

For instance, while renovating a workspace, it’s essential to consider sound-absorbing materials that help keep noise from leaving the space. In contrast, when constructing distraction-free communal workspaces, blocking out outside noise and absorbing and masking sounds within the office is crucial.

Applying the importance of acoustics in interior design can be simplified using the ABC method: Absorption, Blocking, and Covering.

1. Absorption

The ideal way to control noise creation within the workspace is by implementing sound absorption techniques as they shorten the time taken by sound to fade out. Here are some ways to promote the absorption of sound:

  • Using upholstered furniture like soft chairs, sofas, high-rise chairs, etc.
  • Soundproofing office walls and ceilings with acoustic panels
  • Decorating walls with pinboards, canvas pictures and fabric coated frames
  • Hanging false curtains and tapestries
  • Insulating the floor with acoustic underlays, carpets, rugs and sound reduction pads
  • Placing sound-absorbing indoor plants in noisy areas
  • Adding cushions and pillows on chairs and sofas

2. Blocking

Blocking using a barrier to prevent sound transmission from one area to another is a great way to control internal and external noises.

Workspace design and layout play a vital role in blocking internal noise. Creating designated quiet spaces, study zones, breakout areas, etc., using upholstered materials within an open-plan office minimise the spread of noise to and from these areas. You can opt for acoustic room dividers to break large open floor offices and create a barrier between the sound source and work areas. Screens are also a great way to block sounds coming towards or going out from your desk while providing some level of privacy.

If you use sound-blocking materials like concrete in the building structure during construction, you can lower the level of external sounds penetrating your building. In the case of pre-built spaces, building bookcases against the walls block a fraction of the noise that’s in the workplace.

3. Covering

The most common noise in an office space is from people talking, which isn’t too loud, yet hinders your focus. Covering or masking is an efficient way to control such noise in the workspace.

Sound masking uses an ambient sound of the same frequency as human speech in the background. These soothing sounds and other soundproofing techniques enhance office comfort by reducing distracting noises and protecting speech privacy. A sound masking system implemented throughout the workplace helps create an ambient atmosphere to get work done effectively.

These strategies reinforce the importance of acoustics in interior design by creating a more controlled sound environment.
