Available with a variety of connections, allowing the module to easily be designed into new equipment, or retro-fitted to existing products. The module has an integral microcontroller, connected to a small keyboard assembly. The microcontroller and keyboard provide single button operation of all the module's functions. The button switches the noise cancellation on/off and changes the DSP noise cancellation level. In addition the unit stores the last used DSP level, so when power is re-applied the unit will default to the last used setting.

bhi Noise Cancelling Headphones
(Not DSP)

$129.00 AUD
Learn More

These headphones reduce the ambient background noise to allow you to listen to the program source peacefully.
The headphones employ microphones to monitor the ambient noise. These microphones are wired out of phase and feed a differential amplifier which generates an opposing signal to that of the unwanted noise. This signal then cancels out the unwanted background noise.
The headphones effectively remove noise such as blower noise, ambient noise, jet engine noise or music from another room.
The headphones are supplied with an aircraft adapter, so you can now listen to the film, or CD player without all the jet engine noise.
