Our Technology

  • The ALT system uses a probe to play and measure sound. The size of any leaks is determined by comparing the returned sound with the emitted sound. These values are then used to calculate a Personal Attenuation Rating (PAR), a unique value that reflects the amount of attenuation specific to the client and their hearing protection.
