Take you to understand Communication earmuffs
Communication earmuffs are similar to amplification earmuffs:
They offer good attenuation of ambient noise,
and the incoming communication signal is amplified to a comfortable level,
usually with a limiting circuit to prevent too much gain.
The difference, however, is that while amplification earmuffs obtain their input signal from built-in microphones on the earcup,
communication earmuffs obtain their signal from an external radio source.
These earmuffs have moved from traditional hardwire connections (plugged into a communication radio)
to wireless systems utilizing FM or Bluetooth technology.
Earmuffs can be configured for listen-only or two-way communication, usually with an attached boom mic.
Applications that require communication earmuffs are typically found in forestry, mining, aviation, construction,
first responders and military.
But it is critical to test the configuration before purchase to ensure the earmuff is compatible with the user’s needs and hardware.
