Some users looking for smaller, "in-ear," two-way radio communication systems will opt for this unit - custom, or non-custom-fit dual pick-up VIP System with Dynamic Active Hearing Protection technology.
Each earpiece contains a miniature loudspeaker and two miniature microphones. These microphones pick up the user's voice and the surrounding noise levels. These two contrasting signals are then mixed at different ratios.
Using blind source separation (BSS) technology, speech level patterns are then extracted and applied with noise cancellation to provide an effective understanding in surrounding noise levels up to 115dB.
When there are minimal active noise levels, the unit becomes "acoustically transparent." The user can hear all environmental sounds as if they were not wearing any protection at all. This also decreases the need to remove the hearing protection from their ear(s) at anytime they are being worn.
Industries this technology is being effectively used within include racing, law enforcement/military, industrial, motorcycling, fire fighting, EMS/first responders, etc.
Features include:
- Instant attenuation of all dangerous sounds (including impulse noises) to a safe in-ear level
- Speech transmission up to 115dB
- Localization of life saving warning signals
- Flexible connection to various radios
- Optional waterproof "wireless" PTT's (Push-to-Talk) available
- Units come complete with chest ptt (push-to-talk), portable radio connection
Costs: Depends on radio connection and ordering with or without "custom-fit" earpieces and wireless PTT's. Please send us an email or call for further details and pricing options.
