Wolfson Microelectronics have become a collaborator in the EARS project.
Newly developed insert earphone infrasound source provides high dynamic range from 10 to 130 dB SPL with very low harmonic distortions in the desired frequency range from 2 to 125 Hz...
Artificial ear canal design Both the acoustic input impedance and the acoustic transfer impedance of the ear simulator must be as close as possible to the ones of real ears. These two conditions can be satisfied in two steps...
A MEMS ultrasound transmitter operating at 25 kHz does not interfere with magnetoencephalography recordings of brain magnetic fields...
This time with interesting articles on the development of a high-output infrasound source, the production and testing of in-ear ultrasound transducers, news on the design of the universal ear simulator and a business card of the...
The 2nd project meeting will be held in Kopenhagen (Denmark) at 16/17 April.
