Acoustically tested
Measured noise reduction around 4 kHz
The Nũro Hoodie is designed to make stimuli feel softer and easier to manage, not to block the world out completely. Sharp sounds can be especially draining, so the acoustic story focuses on the frequency range where sound is often experienced as piercing or irritating.
-12 dB @ 4 kHz
Measured noise reduction around a frequency where irritation often peaks.
This page brings the proof behind that claim together. Use the video below as a short explanation of what was tested, why 4 kHz matters, and how the result supports Nũro's goal: fewer stimuli, more comfort.
