1 System Description

QUIETPRO is a digital lightweight, intelligent hearing protector and communication terminal for use by noise
exposed personnel. The main components of the system are:
• A control unit with the connectors and push-buttons
• A headset with the required transducers (microphones and loudspeakers)
• High attenuating eartips for sufficient hearing protection
• A radio cable for connection to the appropriate radio system
• An external power supply for battery charging
QUIETPRO is equipped with a user-friendly voice feedback system and indicator lights. Voice messages are given
to guide you through the steps in the menu system and will be used to communicate warnings and alerts.
QUIETPRO is designed to provide the best possible situational awareness and communication while at the same
time protecting the hearing. The unit analyses the surrounding sound and adapts the hearing protector continu-
ously to achieve this. This means that QUIETPRO only attenuates surrounding sound when needed and to the
degree that is needed. The control unit includes volume control buttons, allowing you to reduce or increase the
level of the surrounding sound.
The product uses a range of techniques to protect against noise-induced hearing loss, including high attenuating
eartips, adaptive hear-through, impulse noise protection, and digital Active Noise Reduction (ANR) to increase
attenuation of low frequency noise. QUIETPRO has a built-in fit test that alerts you at start-up if the eartips are not
properly inserted in each earcanal. The system monitors the personal sound exposure based on measurements
from the microphones inside the earpiece. These microphones capture the sound on the inside of the protective
seal, and therefore can be used to calculate the precise personal sound exposure without the need to measure or
estimate the sound attenuation properties of the hearing protection device.
HONEYWELL SAFETY PRODUCTS
Loudspeaker:
Presents an optimal mix of sound from the surroundings and the
communication system to the ear. It is also used for digital ANR.
Eartip:
High quality protective foam eartip seals off the earcanal from
ambient noise. Two special sound ports/pipes transfer sound
between the transducers and the earcanal.
Inner microphone:
Captures the sound of the human voice present in front of the ear
drum and enables radio communication without an external micro-
phone.
Outer microphone:
Situated on the outside of the hearing protection and captures
sound from the surroundings.
