White Noise
White noise has equal energy at every audible frequency. It masks sudden noises effectively, but its high-frequency content can feel 'sharp' or harsh — which is why many listeners prefer pink or brown noise for sleep. Good for infant sleep, office focus, tinnitus masking.

What you're listening to
A smooth, full-spectrum hiss with equal power density from low bass to high treble. No pitched elements, no rhythm — just an even wash of sound. Loam's white noise track is loop-seamless and mastered to −16 LUFS so you can run it at bedtime without peaking.
Why it works
White noise is the most-studied masker for auditory-sensitive sleepers. Its flat spectrum covers the widest range of interrupting sounds, from low rumbles to sharp clicks. Research on infant sleep consistently finds faster sleep onset with white noise present. For adults, pink and brown noise tend to feel more comfortable — white noise's high-frequency content can feel tinny over long sessions.
Best for
- infant sleep
- masking office chatter
- tinnitus relief
- short-term focus
One caveat
For long-duration listening, pink or brown noise usually feels better — white noise's treble content can accumulate ear fatigue over several hours.
