Acoustic Test Chambers
High-performance acoustic chambers provide a consistent, controlled environment for engineering, product development, and quality control. These specialized enclosures ensure accurate, repeatable data for simple quality screening and high precision acoustic measurements alike. Every acoustic test chamber is engineered to meet strict ISO standards or custom-built to your facility’s exact technical specifications.
What is an Acoustic Chamber?
An acoustic chamber (sometimes referred to as a soundproof chamber or sound testing room) is a specialized, isolated enclosure engineered to test the acoustic properties of products, components, or materials without external sound interference. Depending on your precise testing protocols, we offer two primary configurations.
Anechoic Chambers
Anechoic chambers are acoustical enclosures where the walls, floor, and ceiling provide up to 100% absorption of the incident sound energy, making the internal environment virtually echo-free. These rooms are constructed with a noise control outer shell made from our modular panels or masonry walls, and interior surfaces lined with anechoic wedges.
Reverberation Rooms
Reverberation rooms are the exact opposite of anechoic chambers. They are designed to reflect rather than absorb sound energy. These chambers create a highly reverberant acoustic environment while maintaining excellent sound isolation from any external ambient noise.
Critical Design Considerations
Custom configurations mitigate common environmental challenges to ensure testing integrity. Every high-performance design directly addresses:
- Ambient noise levels
- Structural vibration isolation requirements
- Silenced ventilation systems

Benefits of an Acoustic Test Chamber
Investing in a professionally engineered acoustic chamber delivers the precise, controlled conditions necessary for rigorous performance verification.
- Uncompromised Data Accuracy – Establishes a highly controlled, repeatable testing environment to ensure your sound data collection is consistent across repeated tests.
- Maximum Echo Elimination – Delivers up to 100% absorption of incident sound energy, achieving a reflected sound pressure level of 10% or less in an anechoic chamber environment.
- Complete Environmental Isolation – Provides superior sound isolation from external environment noise and structural vibrations that would otherwise skew low-frequency test data.
- Regulatory Compliance – Ensures your sound testing room meets strict ISO Standards and precise internal quality control benchmarks.
