Acoustic Room

Acoustic rooms and noise control

Introduction: SP SONIC designs, builds and verifies acoustic rooms and noise control products for product testing, production lines and buildings. Select a product to see details.

Anechoic Room

Anechoic Room

A room lined with sound-absorbing wedges to create free-field conditions for precision acoustic measurement and product testing. Available as full anechoic or semi-anechoic with a reflective floor.

Our process

Acoustic room projects from concept to certification

  1. 1

    Concept

    Test purpose, products and target background noise.

  2. 2

    Design

    Room layout, structure, HVAC and services.

  3. 3

    Acoustic Calculation

    Absorption, isolation and cut-off frequency calculations.

  4. 4

    Construction

    Fabrication and installation of the acoustic room.

  5. 5

    Measurement

    Background noise and free-field qualification tests.

  6. 6

    Certification

    Test report against the specified standard.

Standards applied where appropriate

ISO 3744 / 3745ISO 26101-1ISO 3741IEC 61672JISASTM

The standard for each room is agreed with the customer according to the test purpose.

Standards & Quality

Work referenced to international standards

Measurement and design follow the standard that applies to each project.
