Pods: Acoustic standards and soundproofing

Working in peace makes all the difference. That is why all our pods are tested according to ISO 23351-1, the global standard for measuring the acoustic performance of office pods.
It is your guarantee that the product you are buying corresponds to your expectations.

Summary

ISO 23351-1 Standard
The global reference for measuring the acoustic effectiveness of booths and comparing products on a reliable basis.
Measured Performance
Our booths offer an average reduction of 28 dB, which means a transition from a noisy open-plan office to a quiet space.
Comfort/Acoustic Balance
Classified B, our acoustic booths combine effective isolation, smooth ventilation, and compact design.

Understanding the ISO 23351-1 standard

Noise is one of the main barriers to concentration at work.

To objectively compare sound isolation solutions, a common method was needed: that is the purpose of ISO 23351-1, reference in the market since 2020. ISO 23351-1 is a technical document that defines the criteria for evaluating the soundproofing performance of acoustic pods.

It takes into account several factors to ensure optimal noise reduction.

The standard uses a unified protocol to measure how much sound escapes and enters the pod, resulting in an overall sound attenuation index.

Thanks to this standardisation, products can now be compared on a fair and reliable basis.

 

How is performance measured?

The standard ranks acoustic pods from A+ to E, based on their ability to reduce speech and surrounding noise. The closer the rating is to A, the better the sound isolation.
At Work With Island, our pods are rated B — a deliberate choice.

 

What does –28 mean?

Our pods offer an average sound reduction of 28 dB.
In practical terms, that means moving from a noisy environment (like a busy open space at 70 dB) to a quiet one (around 40 dB — similar to a calm office or library).

Good to know


Our acoustic pods have a B rating by design: this category offers the best balance between acoustic performance, interior comfort and effective ventilation. Booths with a higher rating often become more cumbersome and less modular, and are much more expensive without offering any significant benefits for everyday use.

The benefits of good acoustics

  • Focus and productivity
    Less noise, more concentration. Acoustic pods create real bubbles of serenity — perfect for focusing, taking a call, or working together without disturbing others.
  • Well-being at work
    A quieter environment reduces stress and improves focus and communication.
  • Guaranteed privacy
    Conversations stay private — whether it is a sensitive discussion or a team video call. At Work With Island, we aim for the right balance between calm, comfort, and common sense. Because the best pod is not the one that blocks out every sound, but the one that fits naturally into your workspace.

Frequently Asked Questions

What are the technical criteria of this standard?

The standard evaluates performance based on several lab-measured criteria.


The two main ones are:

  • Sound pressure level, which measures the amount of noise inside and outside the pod. It indicates how effectively the pod blocks sound transmission.
  • Sound reduction index, which shows the pod’s ability to reduce external noise and create a quiet interior environment.

Is ISO 23351-1 certification mandatory?

No, it is not mandatory, but it has become the international benchmark for assessing acoustic pods.

It ensures that all manufacturers follow the same testing protocol, guaranteeing transparency and reliability.

What is the difference between 25 dB and 30 dB of reduction?

The decibel scale is logarithmic, meaning small numerical differences correspond to big differences in perception.

A pod with 30 dB attenuation isolates roughly twice as much as one with 25 dB.
