Pin(na) your ears back
 | Press Release: |  |
| Jun 16, 2015 — To simplify testing the effects of earphone noise for audio and telecom engineers, Brüel & Kjær has modified the structure of the ear pinna simulators used with its Head and Torso Simulator (HATS). Designed as replicas of the human ear, the new pinnas (Types DZ-9773 and DZ-9774) have been altered to a conical shape merged with a cylinder within the ear canal entrance, making it easier for engineers to seal earphones into the pinna during tests. The symmetrical pinnae are utilised with Bruel & Kjaer’s Head and Torso Simulator (HATS), Types 4128C and D, which consists of a dummy with built-in ear and mouth simulators, to provide a realistic replica of an average, adult human head and torso. Bruel & Kjaer’s HATS system is used to investigate the external acoustic effects from headsets, microphones, headphones, hearing aids, audio conference devices and hearing protectors. The mannequin also has an adjustable neck making it ideal for testing mobile and cordless telephone handsets. More information about Bruel & Kjaer’s HATS is available on www.bksv.com Ends About Brüel & Kjær Brüel & Kjær helps solve sound and vibration challenges, and develops advanced technology for measuring and managing sound and vibration.
