MAA03 Audiometer1.This is an affordable, high-precision audiometer screening type2.this paragraph audiometer Operationsimple
This is an affordable, high-precision audiometer screening type. Can be used to end the hearing when the hearing aid fitting evaluation,
and site services. Can also be used for schools, industrial and mining enterprises, military units, driving school,
training, rehabilitation centers and units for deaf children of hearing officers to conduct rapid screening, is very
convenient to carry. This paragraph can perform all standard audiometer audiometer testing, language listening test, depending
on the structure of a variety of special testing. The design of this paragraph audiometer to an advanced 24-pixel-based digital signal processing, it can produce very high quality signal, and has a lot of refraction. Operation is very simple and intuitive. Can clearly display the current status. Button and select the type of
devices are low noise. Sound level, frequency and other information are clearly displayed on the monitor. Input
signals can be provided internal or external microphone. Has a feature that language listening test, the mask
signals and language signals can be detected while providing to the ear, that "Noise language detection." There are three output options: standard headphones (AC), bone conduction (BC), and special output (SF),
can be connected to the free zone speakers or headphones. Audiometer in this paragraph on the various types can be calibrated headphones. Audiometer in this paragraph can be used as both mobile devices and also as a desktop
device (fixed installation) to use. Audiometer in this paragraph is simple, all-keyboard setup and operation. Monitorl:
Left and right sides of the monitor have an output LED, when the choice of detection signal is transmitted to
the corresponding ear, the display is shown. In the audio detection process, the display shows the uplink to
dBHL to the left ear and right ear quantitative provide strength.
Specifications:Channel: two independent channelsFrequency: air conduction, bone conduction and the standard free field frequency of 11,125-8000Hz, bone conduction 250-6000Hz, the error is less than ± 1%.Masking: pure tone test ipsilateral white noise.
