7 acoustics tips for a calmer office

7 tips for good acoustics

A.M. Acoustics solves the entire puzzle of sound

After more than 20 years in the industry, AM Acoustics has built up considerable experience. This is made clear when Head of Sales Andreas Hultfeldt, Creative Director Johan Götesson, Site Manager...

The reverberation time is the time it takes for a sound to become inaudible. A long reverberation time can be distracting and make it difficult to hear people speak and to maintain concentration, which causes stress. At AM Acoustics, we often work on spaces such as offices, schools and restaurants, where a short reverberation time of around 0.5 seconds is preferred. Here is seven simple ways on how you can improve the acoustics in your office.

#1 Sound absorbing wall

With its 3D structure, NIVÅ absorbs and diffuses sound waves, giving a shorter reverberation time and a more comfortable acoustic.

#2 Screen beside the printer

Absorbs printer sounds at the noise source, which increases the acoustic effect. It also provides a nice visual screen.

#3 Workplace screen

Here is an example with patented THE RISING floor and table screens. If necessary, a sound-absorbing table screen can be pulled up.

#4 Sound absorbing ceiling

Reinforces the existing ceiling with better sound absorption directly above the workplace (noise source). Provides a visual effect and stops sound propagation.

#5 PRINT behind the coffee machine

A sound-absorbing picture reduces the sound from the coffee machine. The absorbent is more effective when placed close to the source of the noise.  

#6 Curtains

A good addition that eliminates sound reflections from hard glass surfaces. Take up a colour scheme or reinforce it with an accent colour.

#7 Furniture and plants

Furnished rooms have a sound diffusing effect, which is reinforced by plants.

How acoustics works

Absorption

Sound absorbents stop sound waves, leading to a shorter reverberation time. Wall and ceiling solutions are often used because they can cover large areas of a room without harming the room’s character. The large areas are supplemented with locally positioned sound absorbents. These will ideally be close to the sound source, e.g. a print hung at speaking height beside a conference table. 

Reflection

Hard surfaces such as glass reflect sound. Acousticians can make use of this property, either in places such as concert venues where it is preferable to avoid electric amplification, or to reduce sound levels by stopping the sound from getting through. See tip #5 on curtains that reduce sound reflections from hard glass surfaces.

Transmission

An important part of acoustic design is sound transmission, which determines how much sound will pass through the ceilings and walls in a building. Good wall and ceiling absorbents help to reduce transmission, so that unwanted sound does not spread from room to room. 

Diffraction

Sound waves curve round objects that are “in the way”, a physical phenomenon that sound waves share with all kinds of waves. Long sound waves curve more than short ones. For example, it is mostly the bass that can be heard outside a nightclub. Pay attention to diffraction when you want to have different zones in an office landscape where some are quieter than others, for example. Use several screens next to each other to minimise diffraction. 

Diffusion

A diffuser scatters the sound and reflects it in different directions. When correctly placed inside the room, it improves sound quality while also reducing reverberation time. See tip #7 on furniture and plants.
