As you become accustomed to wearing your Unitron hearing aids and meeting with your hearing healthcare professional on a regular basis, you may hear unfamiliar terminology used to describe the features and functionality of your new hearing instruments. Below are some common terms that you may hear.
Audiogram – graphical representation of hearing sensitivity, resulting from a hearing test.
Automatic Listening Programs – customized at fitting, these programs adjust automatically as listening situations change.
BiCROS (Bilateral Contralateral Routing Of Signal) – a hearing instrument (HI) system designed for individuals with no useable hearing in one ear and some hearing loss in their better ear. A transmitter HI microphone located on the poor ear picks up sound from that side and sends it to the receiver HI located on the better ear. The receiver HI on the better ear picks up sounds on the better side with its microphone. The sound from both sides of the wearer is then combined and amplified in the receiver HI so it can be heard in the better hearing ear.
Binaural Hearing – use of both ears (right and left).
CROS (Contralateral Routing Of Signal) – a hearing instrument (HI) system designed for individuals with no useable hearing in one ear and normal hearing in their other ear. The transmitter HI located on the poor ear picks up sound from that side and sends it to the receiver HI on the better ear. The receiver HI delivers the sound to the normal hearing ear.
Custom Styles – custom-made hearing instruments that fit directly in the ear. These range in size from fitting deeply inside the ear canal to fitting securely in the outer ear and are often referred to as in-the-ear (ITE) products.
Decibel (dB) – a unit of measurement of the loudness or strength of a signal, commonly noted as dB. The lower the dB, the quieter the sound: a whisper is about 20 dB, a normal conversation is about 60 to 70 dB.
Directional Microphone – puts priority on the sounds directly in front of you, while suppressing background noises from other directions.
Adaptive directional microphone – suppresses moving noise sources (e.g. a car driving by)
Fixed directional microphone – suppresses fixed noise sources (e.g. an air conditioner)
DuoLink – wireless-enabled feature that allows a program or volume adjustment on one hearing instrument to be automatically synchronized in both hearing instruments.
Hertz (Hz) – a unit of measurement of frequency. Humans with excellent hearing can hear sounds from 20 Hz (very low-pitched sounds) up to 20,000 Hz (very high-pitched sounds). Most speech sounds are between 250 Hz and 10,000 Hz.
MyMusic™ – specialized setting to enhance experience of listening to music.
Occlusion – perception of increased loudness of low-pitched sounds when the outer ear is somehow blocked or plugged (for example, by a hearing aid) leading to a "plugged-ear" feeling. Often it is described as a hollow or echoing sound when speaking.
Smart Control – convenient and discreet hand-held control with more functionality than a typical remote control.
SmartFocus™ – powerful and unique Unitron feature that lets you either focus on the sounds in front of you, or maintain an awareness of sounds all around you, depending on your listening needs. Adjust smartFocus™ for increased clarity or more listening comfort.
Speech Enhancement – identifies and increases the amplification of speech, improves the clarity and ease of listening and reduces the need to adjust volume.
uDirect™ – neck-worn accessory that delivers audio directly to both wireless hearing instruments, allowing hands-free operation and connection to a variety of Bluetooth® enabled devices, plug-in audio devices and FM transmitted signals.
Unifi™ Wireless System – allows automatic communication between hearing instruments and connection to audio devices and cell phones.
Ultra-Small Behind-the-Ear – one of the most discreet styles of hearing instruments. It is more than a third smaller than traditional behind-the-ear styles.
