Singing bowls, tuning forks, white noise: which sound for which need?

The world of sound therapy is full of different instruments and sounds. Here is how to tell them apart and match them to your needs.

Singing bowls

Tibetan (metal) or crystal bowls produce rich, long, enveloping harmonic sounds. Valued for meditation and deep relaxation, they create an atmosphere that invites letting go. Their appeal lies as much in the felt vibration as in the sound heard.

Therapeutic tuning forks

Tuned to precise frequencies, they are used by some practitioners placed on the body or near the ears. The experience is very localised; scientific evidence remains limited, but many report a centring and relaxing effect.

Coloured noise

• White noise: all frequencies at equal intensity — ideal to mask noise and focus
• Pink noise: softer, often used for sleep
• Brown noise: even lower, enveloping, soothing

Pure frequencies and beats

Digitally generated, they allow targeted, reproducible sessions. This is the approach of the Sound Doctor app, which synthesises in real time sounds tailored to a body zone or a need, with no audio file.

How to choose?

For focus, think white or pink noise. For sleep, brown noise or very slow music. For meditation, bowls or harmonic pads. The best sound remains the one you enjoy: try, observe your reactions, and build your own palette.
