ELF-442P | RITM

ELF 442P – are 4-channel digital BTE hearing aids with 4 adjustable listening programs; they are suitable to compensate mild, moderate and severe hearing loss.

FUNCTIONS AND ADVANTAGES:

  • WDRC (wide dynamic range compression) with amplification control for different levels of input signals, compression ratios and thresholds;
  • Adaptive AGC (automatic gain control) sets up a triggering threshold and adjusts its gain to achieve a constant signal level at the output effectively;
  • Active low-pass and high-pass filters increase the audibility of high-frequency and low-frequency acoustic information;
  • Low-level noise control function allows to control the degree of low-level ambient noise suppression and microphone noise reduction;
  • Adaptive function of acoustic feedback cancellation identifies adverse whistling tones and eliminates them before they start to distort listening experience;
  • Induction coil eliminates background noise and echo by sending the audio signal directly to the hearing aid without extra equipment or devices;
  • 4 autonomously adjustable listening programs;
  • 8-band graphic equalizer;
  • Acoustic (beep) indicator for switching listening programs;
  • Acoustic (beep) low battery indicator;
  • Direct audio input (DAI) allows an external source to be directly connected as an input that bypasses the microphone;
  • Compatible with cell phones, computers, etc. via Bluetooth devices with a hearing loop.
