Ear canal care and acoustic signal processing

The ear cleans itself. Fine cilia continuously transport earwax outward. Cotton swabs often push these deposits back in front of the eardrum. This reduces sound pressure and disrupts sound conduction. A damp cotton cloth is sufficient for the outer ear. Special rinses with lukewarm water dissolve solid residue without pressure.

How the components work

Hearing devices capture ambient sound through tiny microphones. A digital processor splits the signal into frequency bands. Muffled frequencies receive targeted amplification. The receiver transmits the vibrations directly into the ear canal. A zinc-air cell supplies the necessary voltage with a stable discharge curve. Oxygen activates these cells once the protective tab is removed.

• Microphone: Captures air pressure differences and converts them into electrical charge.
• Signal processor: Filters background noise without delay.
• Silicone earpiece: Holds the housing securely in the ear canal and provides an acoustic seal.

Protection from moisture

Earwax and sweat attack sensitive transducers. A stainless steel filter in front of the sound outlet blocks particles. Replace this filter regularly. This extends the service life of the receiver.

Calm handling in everyday use

Always insert the device with a gentle twist. Do not use excessive pressure. The grade 40 silicone material yields flexibly and adapts to body warmth.
