T-REX 4UP | RITM
T-REX 4UP – is a 4-channel digital BTE hearing aid with 4 adjustable listening programs; it is suitable to compensate moderate, severe and profound hearing loss.
FUNCTIONS AND ADVANTAGES:
- Secure case;
- Adaptive directional microphones allow to achieve better speech intelligibility in various acoustic situations and stronger sound localization;
- Adaptive noise reduction system successfully reduces ambient noise and helps to focus on a single voice to facilitate stable acoustic environment;
- Adaptive function of acoustic feedback cancellation identifies adverse whistling tones bands and eliminates them before they start to distort listening experience;
- WDRC (wide dynamic range compression) restores audibility for weak sounds and simultaneously restores some of the normal loudness perception that is lost with recruitment;
- 4 autonomously adjustable listening programs;
- 12-band graphic equalizer;
- Low-level noise control function allows to control the degree of low-level ambient noise suppression in each channel and microphone noise reduction;
- Acoustic (beep) indicator for switching listening programs
- Acoustic (beep) low battery indicator
- Telecoil program allows making telephone calls
- Compatible with cell phones, computers, etc. via Bluetooth devices with a hearing loop
