Acoustic chambers
Acoustic anechoic chambers: silence you can measure in.
The same two ideas as in an EMC chamber, applied to sound: keep outside noise out, and stop the inside surfaces from reflecting.
Two types
- Anechoic chamber: absorbing wedges on all surfaces, with a suspended walking grid, for free-field measurements
- Hemi-anechoic chamber: absorbing walls and ceiling with a hard, reflective floor, for products that normally stand on the ground
What decides the design
The lowest frequency to be measured sets the depth of the absorbing treatment, and the background noise you need sets the sound insulation of the shell and its vibration isolation from the building.
Acoustic and EMC together
Some products need both electromagnetic and acoustic measurements. Tell us what you need to measure; acoustic chambers are designed and supplied through partners, on request.
