How ENC Works:

ENC leverages sophisticated algorithms and strategically placed microphones to filter out unwanted background noise during calls. Here’s a breakdown of the process:

1. Sound Capture: The H9’s built-in MEMS (Micro-Electro-Mechanical Systems) microphones capture both your voice and the surrounding ambient noise. These microphones are tiny, highly sensitive devices that convert sound waves into electrical signals.
2. Signal Processing: The captured audio signals are then processed by a dedicated chip that utilizes advanced Digital Signal Processing (DSP) algorithms. These algorithms are designed to differentiate between your voice and background noise based on their distinct frequency characteristics and patterns.
3. Noise Suppression: The DSP algorithm identifies and attenuates the unwanted noise components, effectively suppressing them in the audio signal. This process is akin to a skilled sound engineer selectively reducing the volume of specific instruments in a recording to highlight the vocals.
4. Voice Enhancement: Simultaneously, the algorithm enhances your voice, ensuring that it is transmitted clearly and prominently to the person on the other end of the call.

The result is crystal-clear voice transmission, even in noisy environments like bustling streets, crowded cafes, or windy conditions. This is especially useful for the many professionals who rely on clear, crisp and reliable communication throughout their day. The effectiveness of ENC can vary depending on the type and intensity of the background noise. While it excels at reducing steady-state noises like traffic or wind, it may be less effective against sudden, unpredictable sounds.
