HMEC 25-6A / HMEC 25-KAP-2

A headset is comprised of two units, a headphone and a microphone. The HMEC 25-6A/-KAP-2 headset is mostly used for communication in aircraft cockpits.

￿The microphone is a high quality back-electret condenser microphone. As per ARINC it receives its operating voltage via a connector from the aircraft´s internal power supply.

￿The headphone is a Sennheiser NoiseGardsystem. This is a dynamic headphone system which, in addition to reproducing the original audio signal, electronically cancels the low frequencies of the ambient noise. This active noise compensation operates on the principle that sound and ”anti-sound“ (in phase opposition) cancel each other out. The NoiseGardcompensation circuitry in the headphone requires an extra power supply, so a battery com- partment has been integrated into the headset cable (see illustration p. 14).

Clearly intelligible communication is ensured, and the pilot no longer has to turn the volume up to overcome ambient noise.

but it is not a medical hearing protection!
