General information, not medical advice. This guide describes what ear plugs do for a person sharing a room with someone who snores, and what published sources say about them. It does not diagnose snoring or recommend treatment for any individual.
Short answer
Ear plugs for snoring work on the listener, not the snorer: they reduce the sound that reaches the ear of the person who is being disturbed, and they do nothing to stop the snoring itself. The NHS snoring page mentions partner earplugs among its suggestions. One published controlled study, a two-month trial of custom-moulded ear plugs in couples, reported improved questionnaire scores for both partners.
Definition and scope
In this guide, “ear plugs for snoring” means ear plugs worn by a bed partner or room-mate to reduce the noise of someone else’s snoring. It does not cover ear plugs worn by the snorer, hearing protection for workplace noise (see hearing protection types), or devices intended to treat snoring or sleep apnoea.
The NHS describes snoring as caused by “things such as your tongue, mouth, throat or airways in your nose vibrating as you breathe”, which happens as these parts relax and narrow during sleep (NHS, Snoring, checked 2026-10-30). Because the sound comes from that vibration, an ear plug cannot change it. It can only change how much of it the listener hears.
How ear plugs are used for a snoring partner
The NHS page on snoring includes the suggestion to “consider asking your partner to use earplugs if your snoring affects their sleep”. Ear plugs act on the listener’s side of the problem: they change how much of the sound the partner hears, not the snoring itself.
What the controlled evidence shows
Robertson, Loughran and MacKenzie published “Ear protection as a treatment for disruptive snoring: do ear plugs really work?” in the Journal of Laryngology and Otology (2006;120(5):381-4, PubMed 16696877, checked 2026-10-30). Key points of the design and results as reported in the abstract:
- Eligible couples took part in a two-month trial in which each partner used custom-moulded ear plugs.
- Five questionnaires were completed by patients and partners at the start and after two months: the snoring outcomes survey or spouse/bed partners survey, the Epworth sleepiness scale, the general health questionnaire-12, the Nottingham health profile and the Golombok-Rust inventory of marital status.
- After two months there was a significant improvement in the snoring outcomes survey score for patients (p = 0.005), the spouse/bed partners survey score for partners (p = 0.001) and the Epworth sleepiness scale for partners (p = 0.004).
- The authors concluded that for selected couples, ear plugs represent an effective short-term treatment for some of the social effects of disruptive snoring.
Read the finding within its limits: the plugs were custom-moulded, the trial ran for two months, and the couples were selected. The abstract does not report results for foam or other ready-made ear plugs, so the trial cannot be read as evidence for them.
Types and related concepts
The trial above used custom-moulded plugs, and that is the only type for which this guide reports evidence. For how ear plugs differ from earmuffs and canal caps in general, see Hearing Protection Types. Ear plug packaging for workplace use often carries a rating; the rating system is explained in Noise Reduction Rating (NRR) on earplugs and NRR vs SNR. Those ratings describe laboratory attenuation of workplace noise. They are not a measure of how well a plug will suit sleeping beside a snorer, and this guide does not give a decibel target for that use.
Where it matters: noise versus health signal
For lab, clinic and supply staff answering questions about ear plugs, the useful distinction is between a noise question and a health question. Ear plugs address only the first. The NHS notes that snoring can sometimes be a sign of sleep apnoea, a separate condition in which the airways become temporarily blocked during sleep. This guide does not cover diagnosis or treatment of snoring or sleep apnoea; the NHS Snoring page is the place for that information.
Common misunderstandings
Ear plugs treat snoring
They do not. They lower what the listener hears. The snorer’s airway vibration, and any underlying cause, is unchanged.
The trial proves any ear plug works
The published trial tested custom-moulded plugs in selected couples over two months. It does not extend to every type of ear plug.
FAQ
Do ear plugs for snoring really work?
In one two-month trial of custom-moulded plugs, partners and snorers reported significantly better snoring-impact and sleepiness scores (Robertson et al., 2006). The authors described them as an effective short-term treatment for some social effects of snoring in selected couples. They do not reduce the snoring itself.
What does the NHS say about ear plugs and snoring?
The NHS snoring page includes asking a partner to use earplugs among its suggestions when snoring affects their sleep (checked 2026-10-30).
