Key Takeaways
Usually a moderate amount. Most guides quote the SNR 16–30 dB band, and at SNR 24 a 60 dB conversation reaches the ear at roughly 36–40 dB. Quieter, not silent.
A deep 30 dB+ foam seal typically makes your own chewing and breathing louder, and it feels so cut off that people tend to leave the plugs in for hours. NHS guidance advises against wearing earplugs all the time.
It brings it down to about 21–23 dB at the ear. You may still notice someone chewing right next to you, just at a much lower level.
No. An earplug lowers the level reaching the ear and nothing more, and it does nothing about a movement you can see. A GP is the right person to talk to about the reaction itself.
For a moment you choose: a meal, a train journey or a 45–90-minute focus block. Then take them out, and stop using them if you notice pain or itching.
For most people, yes. A typical 45 dB chewing sound lands at about 21–23 dB with an SNR 24 earplug. That is quieter, not silent, so chewing right beside you may still be noticeable.
SNR is the UK and EU rating, tested under EN 352-2, and NRR is the US rating. The test methods differ, so the same earplug typically shows an SNR about 3–7 dB higher than its NRR.
Not usually for trigger sounds. A deep foam seal typically makes your own chewing and breathing louder, and the stronger isolation makes it tempting to wear them all day, which NHS hyperacusis guidance advises against.
Yes. A passive earplug lowers every sound, voices included. At SNR 24 a 60 dB conversation lands at about 36–40 dB, so you can still follow it because it is loud enough, while at SNR 30+ it drops to 30 dB or below and talking gets harder.
How many decibels do earplugs for misophonia need? Far fewer than the biggest number on the shelf. A moderate rating of around SNR 16–30 dB covers everyday trigger sounds, and at SNR 24 a 60 dB conversation arrives at roughly 36–40 dB while a 45 dB chewing sound drops to about 21–23 dB. Go much higher and you mostly buy side effects.
On hearing forums, people often say they only want to take the edge off, not shut the world out. The arithmetic below backs that instinct.
At Bollsen, we make reusable silicone earplugs trusted by 1,000,000+ people: German-tested, independently certified 24 dB. Our main guide to earplugs for misophonia covers choosing and using them day to day. Here we stick to one question: how much noise reduction trigger sounds actually call for.
How many decibels do earplugs for misophonia need?
For everyday trigger sounds, an earplug rated somewhere around SNR 16–30 dB is enough, and a mid-range SNR 24 sits comfortably inside that band, because the sounds in question are rarely loud to begin with.
Chewing, sniffing, throat clearing and pen clicks typically measure 40–65 dB at one metre. For comparison, the US National Institute on Deafness and Other Communication Disorders puts normal conversation at 60–70 dBA. Most triggers are no louder than talking.
That low level tells you something. The reaction is to the sound itself, not to how loud it is, so a bigger number cannot switch it off. Earplugs also leave misokinesia untouched, the response some people have to seeing a movement such as jaw chewing or a jiggling foot.
It is also common. A representative UK study of 772 adults found that 18.4% met the threshold for significant misophonia burden on the S-Five questionnaire (Vitoratou et al., PLOS ONE, 2023).

Subtract the rating from the sound level and you get a rough idea of what reaches the ear: at SNR 24, a 60 dB voice lands at about 36–40 dB and a 45 dB chewing sound at about 21–23 dB.
Treat these as indicative lab figures. In everyday use, protection is usually a little lower, and HSE guidance allows about 4 dB for real-world fit.
| Rating | Typical earplug | 60 dB conversation lands at | 45 dB chewing lands at | Occlusion and all-day-wear risk |
|---|---|---|---|---|
| SNR 16 | Low-attenuation reusable | ~44 dB | ~29 dB | Low occlusion. Easy to wear, but a close-up trigger can still stand out. |
| SNR 24 (Life+) | Two-lamella silicone | ~36–40 dB | ~21–23 dB | Moderate occlusion. Voices stay audible because they are loud. |
| SNR 30+ | Foam, 30–35 dB | 30 dB or below | 15 dB or below | Maximum occlusion of your own chewing and breathing. A cut-off feeling that tempts all-day wear. |
Our Life+ (passive SNR 24 dB, H 24 / M 21 / L 19, £29.95) is the middle row. Its attenuation rises with frequency, so higher-pitched sounds come down slightly more than low ones such as chewing, and our guide to how loud common trigger sounds are goes through each sound in detail. Nothing is singled out: every sound simply arrives quieter.
Why can 30 dB+ foam earplugs make a shared table harder?
A 30–35 dB foam earplug seals the ear canal tightly, which typically makes your own chewing and breathing louder by 10–20 dB below about 500 Hz, because those sounds travel through bone and get trapped behind the seal.
That is the occlusion effect, and at a meal it works against you. The room goes muffled while the crunch of your own food fills your head. A correctly sized, deeper-sitting reusable plug typically lessens it, and we explain the mechanism in why you hear your own chewing with earplugs in.
Foam has its place on a loud building site. For trigger sounds at a table, we weigh it against reusable plugs in silicone vs foam earplugs for misophonia.
Isolation has a second cost. The Health and Safety Executive’s guidance on over-protection says protectors that bring the level at the ear below 70 dB in noisy workplaces leave people feeling cut off, and they tend to take them out. That rule is about loud work noise, but the principle carries over: more isolation is not automatically better.
Is it a problem to wear earplugs all day?
For most people it is, and the NHS page on hyperacusis advises against wearing earplugs or ear muffs all the time, because constant use could make you more sensitive to noise, while short-term use may help in very noisy places.
This is where a total-isolation plug backfires. When the world goes very quiet, it is tempting to keep the plugs in for hours. A moderate rating makes it easier to use them for a chosen moment, like the family meal, the train home or a 45–90-minute focus block, and then take them out.
Stop using them if you notice pain or itching. Total silence is rarely the aim for people who also notice ringing in their ears, either, and our page on earplugs for tinnitus explains why a little background sound often suits them better than maximum reduction.
Nights beside a partner raise their own questions, covered in our guide to misophonia and sleep.
What do SNR and NRR mean on the box?
SNR is the single number rating used in the UK and EU under EN 352-2, while NRR is the US rating, and because the two come from different test methods, the same earplug typically shows an SNR about 3–7 dB higher than its NRR. For the full explanation of the standards, see our guide to what SNR and NRR mean, written for sleep but true of any earplug.
Which earplugs suit trigger sounds best?
For most trigger sounds, a reusable plug in the middle of the range is the sensible choice, and that is where our Life+ earplugs sit: passive SNR 24 dB, hypoallergenic silicone, a two-lamella design and a flush fit with no stem.
One pair costs £29.95 and lasts up to 100 uses, about 30p a use. Two packs are £44.95, UK delivery is free on orders over £35, and every order comes with our 40-day money-back guarantee.
Fit matters as much as the number, since a shallow or tight plug changes both protection and occlusion. If you fall between sizes, Life+ with AI ear measurement from two photos sizes the plug to your own ear canal.
When is it time to talk to a GP?
If certain sounds bother you enough to affect work, study or home life, a GP is a good first step, and earplugs work best as one practical tool for chosen moments rather than a whole plan.
A GP can talk through options and refer you on where that makes sense. In England, the Oxford Health Specialist Psychological Interventions Clinic is one NHS service that lists misophonia among the areas it works with.
So which rating should you pick?
Pick a moderate rating, around SNR 24, and use it for a chosen moment rather than all day. The highest number mostly buys you louder chewing inside your own head and a stronger pull to leave the plugs in.
Before you buy, how to choose earplugs for misophonia walks through fit, material and comfort alongside the rating.
