Acoustic Testing is the measurement of sound emitted from the test specimen to determine if the product is operating within the specified noise limits defined by the end user or manufacturer. Acoustic noise measurements are made with specialized microphones placed at different distances and positions around the product in order to quantify the overall sound levels emitted by the test specimen. This testing is required for certain commercial, medical, or telecommunications products to ensure noise limits fall within an acceptable range.
Quest Engineering Solutions’ facilities are equipped with a 13′ x 10′ x 8′ hemi-anechoic acoustic chamber capable of performing a full range of acoustic measurements, including Sound Pressure and Sound Power measurements. Our setup consists of an array of up to 10 microphones as well as state of the art measurement equipment and software.
Quest also offers a variety of additional acoustic tests and the design experience to help you develop quieter products for your customers. Our chamber is able to cancel out all outside noise and provide accurate acoustic measurements.
