Earplugs and White Noise Machines
Published 2026-08-03. Last updated 2026-08-03. Desk research by Kaiser Khan — we have not product-tested earplugs and acoustic masking. This is not a shop review and not medical advice.
In short
Earplugs reduce sound level at the ear canal. Ratings such as SNR or NRR estimate attenuation in decibels under test conditions. White, pink, and brown noise machines add a steady sound field that can mask intermittent noises. They raise the background so sudden sounds stand out less. Attenuation and masking are different strategies. Plugs lower level. Masking covers contrast.

Two strategies for night noise
| Strategy | How it works | Limit |
|---|---|---|
| Earplugs | Attenuate level at the ear | Fit-dependent; comfort varies |
| Acoustic masking | Raise steady background | Does not remove the original noise source |
Using ratings carefully
Laboratory SNR/NRR values assume correct fit. Soft foam plugs need full expansion in the canal. Flanged silicone plugs need a seal. Partial insertion overstates real attenuation.

Frequently asked questions
What does SNR mean on earplugs?
SNR (Single Number Rating) is a European estimate of hearing protection attenuation in decibels under standardised test conditions. Real-world reduction depends on fit and correct insertion.
Is white noise the same as silence?
No. White noise adds sound energy across frequencies. It can make sleep easier in noisy environments by masking, but it is not the absence of sound.
White vs pink vs brown noise?
These labels describe different spectral slopes. White is flatter across frequency. Pink and brown emphasise lower frequencies more. Preference is individual.
