Be Sound,|Not Noise.

We take psychoacoustics seriously. Research, data and sound science to create precise, measurable, result-driven solutions.

Manifesto

"To this day, noise has been the 'Cinderella' of pollution, and people are unaware of the impact it has on health."

Deepak Prasher · Professor of Audiology, University College London

"If you want to find the secrets of the universe, think in terms of energy, frequency and vibration."

Nikola Tesla

Like Tesla and Professor Deepak Prasher, we treat sound as a scientific field: research, data and psychoacoustic principles at the service of performance, intelligibility, relaxation, stress reduction and health.

Psychoacoustics in 60 seconds

Psychoacoustics is the science of how the human brain perceives, interprets and reacts to sound. It explains why two rooms with the same decibel level can feel completely different, and it lets us design the right sound for each goal.

Perception is not measurement

The ear is not a decibel meter. Loudness, timbre and annoyance depend on frequency, context and expectation.

Masking

One sound can cover another. Used with science, it reduces distraction and protects speech privacy.

Sound, emotion and memory

Sound reaches the limbic system before reason. It shifts mood, stress and even visual perception.

Attention and performance

Irrelevant noise steals focus. Well designed soundscapes give back concentration and well-being.
