    Insta ANR - Active Noise Reduction for Aviation and Demanding Environments

    Noise is a common problem especially in military aviation. Cabin noise levels often exceed safe exposure levels and noise degrades pilot performance. Lowered noise levels reduce the risk of hearing damage, improve radio and intercom intelligibility and improve aircrew performance by reducing the effects of noise on focus and decision making.

    Insta ANR provides up to 30 dB of low frequency attenuation and the system can attenuate frequencies down to 30 Hz. The attenuation and frequency response of Insta ANR can be adjusted to suit the application, the noise environment and even a specific user. 

    Insta ANR was developed and tested according to Insta’s AQAP-2110 process.
