Acoustical measurements and instrumentation

For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO.

Here, examples include tweaking an automobile door latching mechanism to impress a consumer with a satisfying click or modifying an exhaust manifold to change the tone of an engine's rumble.

Acoustical measurements and instrumentation range from a handheld sound level meter to a 1000-microphone phased array.
