GRAS 45CA Headphone/Hearing-protector Test Fixture

GRAS 45CA provides the basis for reliable and exact measurements and is designed with

  • A test fixture mounted on a resilient base that reduces the noise floor to a minimum in a typical test situation. Foam plugs and grease are supplied to avoid sound leakage along the cable
  • A test fixture head, made for optimizing the acoustic isolation
  • An acoustic cup and plug for testing the acoustic isolation
  • A range of molded-rubber KEMAR pinnae, e.g. for testing earplugs, can be fitted

The 45CA’s robust design is ideally suited for binaural testing of active and passive earplugs, as well as circumaural hearing protectors.

It is primarily intended for testing the performance of hearing-protection devices such as earplugs and earmuffs (supra-aural and circum-aural) but can also be used for testing sound sources such as earphones and headphones. It is fitted with either microphones or ear simulators, depending on the device to test and the standard to comply with.

GRAS 43AG Ear & Cheek Simulator

43AG is a table top test device for measurements on earphones of various types. It simulates the ear and cheek of a human head as well as approximates the acoustic impedance of an average human ear. It can be used to verify frequency response, distortion, isolation and leakage. Its versatility means that it can be used for testing of both concha and insert types earphones. It can also be used for headphone and headset testing, both circum-aural and supra-aural types. Also, all common types of hearing-aids and telephone handset can be tested with 43AG.
