NTT Sonority is the NTT Group’s first consumer audio brand “nwm” that provides devices and services using the world’s first “personalized sound zone” (PSZ) technology developed by NTT that confines sound only to the ears. to enter the audio industry. On the 9th (Wednesday), two models of personal ear speakers (wired model “nwm MWE001” and wireless model “nwm MBE001”) that minimize sound leakage to the surroundings despite being an open ear type will be released as the first product of the “nwm” brand. Announced.

Takehiko Kawazoe, Vice President of NTT, said, “PSZ technology is the world’s first new technology related to sound derived from the IOWN concept. If sound can be confined to a specific place, the dream of telepathic communication may be realized. There is,” he commented.

Hiroshi Sakai, President of NTT Sonority, said, “nwm is an abbreviation for the New Wave Maker, and it contains the desire to create new sound waves and deliver them to the world. Work from home. We aim to be the audio brand that is the most chosen in the music scene.”
With a view to the global market, NTT Sonority aims to acquire a 10% share of the open-ear earphone market and achieve sales of 40 billion yen by fiscal 2025. Cooperate with Itochu Corporation for global sales.

The wireless earphone market is expected to expand to 4 trillion yen. NTT Sonority estimates that the potential open-year market will reach 400 billion yen.
The PSZ technology is the world’s first technology that reconciles the contradiction of being open but confining sound. Sound is a wave that travels through the air. It has the property that when a certain sound wave is hit by a sound wave of the opposite phase, the sound waves cancel each other out and the sound disappears. Focusing on this property, a special hardware design is used to reproduce sounds limited to a specific area.
