TEAM’s Acoustic Testing – Delivering Sound Data

Sound is a critical product attribute. Consumers often form impressions of the overall quality of a product based on the sound it makes.
In order to achieve a desirable sound quality, you must be able to identify those aspects of a design that can be modified to eliminate specific, objectionable sounds, while retaining other appropriate and desirable sounds. At the same time, there are often government-imposed sound-level standards that must be met.

TEAM conducts three types of acoustic testing:

Hemi-Anechoic Chamber

A hemi-anechoic chamber provides a precise free-field environment in which sound sources can be measured over a reflecting plane. Typical measurements include product noise testing, sound source frequency response, and sound source directivity.
TEAM utilizes a hemi-anechoic chamber to test prototypes during the development phase of a product. This provides a baseline of the prototype’s overall sound pressure level (SPL) and frequency content.Hemi-anechoic chamber

In-Vehicle Acoustic Testing

TEAM performs in-vehicle testing in order to obtain a baseline for the overall sound pressure level (SPL) and frequency content in the vehicle during actual operating conditions.

Production Line Acoustic Testing

TEAM conducts end-of-line acoustic testing for complete assembly verification through comparative frequency analysis. Results are traceable to individual units by serial number which are stored in a secure database.
