The L8-IF 8-Channel Digital Hearing Aid achieves a maximum output sound pressure level (OSPL90) of 110 dB and a high-frequency average (HFA) OSPL90 of 105 dB, providing sufficient amplification power for users with moderate hearing loss. The full-on gain reaches 35 dB maximum and 29 dB HFA, ensuring adequate amplification for speech frequencies while maintaining low distortion levels. Total harmonic distortion remains below 3% across critical speech frequencies of 500 Hz, 800 Hz, and 1600 Hz, ensuring clean, undistorted sound reproduction. The CIC hearing aid device operates efficiently with a battery current of just 1.2 mA, extending battery life and reducing the frequency of battery replacements. The frequency range of 200 Hz to 5000 Hz covers the essential speech spectrum, enabling clear understanding of consonants and vowels across male and female voices.
