Overview - Sensear SM1 Manual Del Usuario

OVERVIEW

The Sensear SM1, SM1x and SM1x SR models hearing defense systems are state-of-the-art hearing
protectors. The systems have sophisticated electronics and algorithms to enhance speech in noisy
environments. As a result, Sensear SM1, SM1x and SM1x SR users do not need to remove their
hearing protection to hear speech in noisy environments.
In addition, the SM1x SR units incorporate FM short range connectivity, Bluetooth technology,
external audio pass-through and two-way radio connectivity. This enables users to communicate
to other SM1x SR users wirelessly, effectively answer a phone call, listen to an MP3 player or use
a two-way radio whilst wearing their hearing protection.
The SM1x unit is functionally identical to the SM1x SR in every respect, with the exception of the
FM short range connectivity. The SM1x communication features include Bluetooth technology,
external audio pass-through, face-to-face and two-way radio connectivity.
The SM1 unit is functionally identical to the SM1x in every respect, with the exception of the
Bluetooth connectivity function. The SM1 communication features include face-to-face and two-
way radio connectivity.
The SM1 Ultra and SM1x (SR) Ultra models include a noise cancelling boom microphone for extreme
noise environments. Standard models may be upgraded by purchasing the Boom microphone
upgrade kit.
The SM1, SM1x and SM1x SR are available in over-the-head headband or helmet mount models.
Helmet mount adaptors are available for a wide range of helmets. See section Helmet Mounts.
The basis of the SM1, SM1x and SM1x SR units consists of advanced signal processing algorithms
that process sound. The output of these algorithms is referred to as the SENS processed sound. In
the SENS processed sound, the speech of nearby speakers is enhanced while at the same time,
the surrounding noise is suppressed. The SENS processed sound is the sound delivered to the
SM1, SM1x and SM1x SR users.
Noise reduction will be adversely affected by anything that impairs the seal of the earmuff cushions
against the head, such as thick spectacle frames, balaclavas, etc. Cushions may deteriorate with
use and should be renewed regularly.
