5.3 Understanding PSZ (Personalized Sound Zone) Technology
The nwm NTT Sonority MWE001 incorporates advanced PSZ technology to create a personalized sound field around your ears. This technology works by:
- Emitting sound waves in opposite phases to confine audio reproduction within a set distance from the user's ear.
- Counteracting sound leakage by playing perfectly opposite audio waves, ensuring privacy without blocking ambient sounds.
This allows you to enjoy your audio content while still being able to hear your surroundings and engage in conversations naturally.
