The science behind
total speech privacy.
NullWave traps your voice sound waves at the source. Here is how acoustic physics and precision hardware keep your words confidential.
Sound Absorption
When you speak, sound waves push air outward. NullWave's inner chamber is lined with high-density reticulated foam that absorbs sound energy before it can travel out into the room.
Direct Mouth Pickup
Digital microphones sit just 12 millimeters from your lips. Because they capture your voice right at the source, your listener hears you in crystal clarity while street noise is physically locked out.
On-Device AI Audio
An onboard low-power audio processor cleans and isolates your voice stream instantly with zero delay, ensuring your dictation and voice calls sound studio-recorded.

Designed for normal conversation
without whispering.
You do not need to whisper, mumble, or cup your hand over your mouth. Speak at your natural conversational volume. The acoustic seal ensures that sound stays within your personal space.
NullWave gives you the acoustic isolation of a dedicated office phone booth, packed into an 88-gram wearable you can carry in your coat pocket.
