AD8320 artificial human head specially designed for simulating human acoustic testing

Everything you need to meet your testing needs

USD 9,700.00

AD8320 is an acoustic artificial head specially designed for simulating human acoustic testing. The artificial head profiling structure integrates two artificial ears and an artificial mouth inside, which has the very similar acoustic characteristics to real human head. It is specially used for testing the acoustic parameters of electro-acoustic products such as speakers, earphones, and speakers, as well as spaces such as cars and halls.
