Key Takeaways
Foam blocks more, around 30 to 35 dB, while reusable silicone lamella earplugs sit at roughly 22 to 25 dB. For short, chosen moments with trigger sounds, many people find silicone easier to live with, because the room stays quieter but present and the plugs go in and out in seconds.
Not automatically. A near-total seal also cuts you off from the room, makes your own chewing and breathing more noticeable, and makes all-day wear tempting, which NHS guidance on noise sensitivity advises against.
Sealing the ear canal holds in sound that travels through the bones of the head, so your own chewing, breathing and voice can seem 10 to 20 dB louder below about 500 Hz. This occlusion effect happens with any sealed earplug and changes with fit and insertion depth.
Foam costs a few pence a pair but goes in the bin after every use. Life+ reusable silicone is £29.95 for up to 100 uses, about 30p a use, while custom-moulded earplugs cost around £100 to £200 up front.
NHS guidance on hyperacusis says not to wear earplugs or ear muffs all the time, because this could make you more sensitive to noise. Use them for a chosen event, take them out afterwards, and stop if you feel pain or itching.
They can be, if you will wear them often for years. An audiologist takes impressions of your ears, the finished plugs cost around £100 to £200, and they typically last four to five years before your ears change enough to need a new pair. For occasional use at meals or on journeys, reusable silicone does the same job for far less.
It depends on the product. Our Life+ earplugs are rated for up to 100 uses, washed with water and mild soap between wears and stored dry in their case. Replace any pair sooner if the silicone tears, hardens or stops sealing.
Custom-moulded earplugs and low-profile silicone earplugs that sit flush in the ear are the hardest to spot. Foam usually leaves a coloured end visible at the canal opening, and wax or putty sits over the entrance where others can see it.
Silicone vs foam earplugs for misophonia comes down to one question: do you want the most silence you can buy, or a quieter room you can still take part in? Foam blocks more sound. It also seals your own chewing in with you, and plenty of people describe the result as a “head underwater” feeling.
Plenty of people weigh this up. A representative UK study of 772 adults found that 18.4 % experienced misophonia at a level that caused significant burden (Vitoratou et al., PLOS ONE, 2023). At Bollsen, we make reusable silicone earplugs trusted by 1,000,000+ people, and this page sits under our wider guide to earplugs for misophonia, comparing the four earplug categories with numbers rather than adjectives.
Does blocking everything help if certain sounds bother you?
Blocking everything is not automatically better for trigger sounds: an earplug that seals the ear canal as tightly as foam lowers outside sound by around 30 to 35 dB, but it also raises the sound of your own chewing and breathing and cuts you off from the conversation around you.
Three things work against the “maximum blocking” idea. First, the occlusion effect: research on earplug occlusion finds it is strongest at low frequencies and depends on the earplug’s type, fit, insertion depth and material (Carillo, Doutres and Sgard, 2021). Even deeply inserted foam still produced a noticeable occlusion effect in laboratory tests (Stenfelt and Reinfeldt, 2007).
Second, isolation. A plug that makes a family dinner almost silent also makes the people at the table hard to follow. Third, habit: the more total the quiet, the more tempting it becomes to keep them in for hours. A common worry we hear is “blocking everything makes me hear triggers more when I take them out”, and that is exactly the pattern NHS guidance warns about.

Foam earplugs give the highest attenuation and the strongest occlusion, silicone lamella earplugs trade a few decibels for reuse and a flush fit, wax and putty cover the canal entrance for a few uses, and custom-moulded earplugs cost the most up front but last for years.
| Earplug type | Typical attenuation | Occlusion (own chewing, breathing) | Discretion | Hygiene | Cost per use (UK) |
|---|---|---|---|---|---|
| Foam (roll-down) | About 30–35 dB | Highest of the four: a full, tight seal | Coloured end usually visible at the canal opening | Single-use, a fresh pair every time | A few pence a pair, paid at every meal or journey |
| Silicone lamella (reusable) | About 22–25 dB | Moderate, varies with size and insertion depth | Low-profile designs sit flush in the ear | Washed with water and mild soap; Life+ up to 100 uses | About 30p (Life+ £29.95 ÷ 100 uses) |
| Wax / putty | About 20–27 dB | Noticeable: seals over the canal entrance | Visible over the entrance of the ear | Picks up lint and hair; a few uses per pair | Low per pair, but replaced after a few uses |
| Custom-moulded | Varies with the mould and material | Depends on how deep the mould sits | Can sit flush and close to skin tone | Washable; replaced every 4–5 years as ears change | Around £100–200 up front; about 16–32p a use at three uses a week over four years |
Attenuation is the column people fixate on, yet higher is not better for trigger sounds, and our guide on how many decibels earplugs for misophonia need explains why the middle of the range usually suits short, chosen moments. The occlusion column covers why you hear your own chewing with earplugs in, which is often the deciding factor for anyone bothered by eating sounds.
Hygiene matters more with reusable types, since a plug that goes in at every meal needs to be clean every time. Our guide on how to clean reusable earplugs applies just as well to daytime wear. Earplugs with a built-in acoustic filter form a separate category with lower ratings and sit outside this comparison.
What does each earplug material mean for trigger sounds?
Foam: the most attenuation, the most occlusion
Slow-recovery foam is rolled thin, pushed in and left to expand, which gives the deepest seal of the four and the highest numbers on the packet. At your own table it can backfire, because your own jaw becomes the loudest thing you hear, and some people say they “can’t wear foam earplugs for more than 20 minutes” before the pressure gets to them. Our guide to foam earplugs covers how they are made and why they are single-use.
Silicone lamella: quieter but present, and reusable
Reusable silicone earplugs with soft lamellae (the stacked, ring-like layers) typically lower sound by 22 to 25 dB. That leaves a 60 dB conversation at roughly 35 to 38 dB and someone else’s chewing at 45 dB around 20 to 23 dB: quieter, not silent. They wash under the tap and go back in their case, and our guide to silicone earplugs explains the material and how long a pair lasts.
Wax and putty: a seal over the entrance
Wax and silicone putty are warmed in the fingers and pressed over the canal entrance rather than pushed deep inside, landing somewhere around 20 to 27 dB. The catch is hygiene and visibility, since they pick up lint and hair, last only a few uses and sit where others can see them. Our guide to wax earplugs goes through how to use them for short sessions.
Custom-moulded: a fit made for your ears
A private audiologist takes impressions of your ear canals, and the finished plugs usually cost around £100 to £200. They are discreet and long-lasting, but you pay for years of use up front and need a new pair after about four to five years. Our guide to custom moulded earplugs covers the fitting process and when they are worth the outlay.
Where does Life+ sit among the four types?
Life+ is a passive, reusable silicone lamella earplug rated SNR 24 dB (H 24, M 21, L 19), German-tested and independently certified to 24 dB under EN 352-2, so it sits in the middle of the attenuation range rather than chasing the highest number. Like most passive earplugs, its attenuation rises with frequency, and the full frequency picture sits in our guide to misophonia trigger sounds.
A voice across the table stays audible because it is loud, not because the earplug lets one kind of sound through. The patented conical two-lamella design sits flush in the ear with no protruding stem, just a small removal tab, so it is one of the more discreet options in the table.
For meals, journeys and study blocks, our Life+ reusable silicone earplugs (SNR 24 dB, up to 100 uses, £29.95) are made from hypoallergenic silicone that is BPA-, PVC- and latex-free, and come in an aluminium keyring case. At up to 100 uses, that is about 30p a use. Two packs cost £44.95, UK delivery is free on orders over £35, and every order carries a 40-day money-back guarantee.
Fit drives occlusion as much as material does, and a plug that is the wrong size leaks sound or presses on the canal. If sizing has been a problem before, there is Life+ with AI ear measurement from two photos (£44.95), the same 24 dB earplug shipped in the size our system picks from two pictures of your ears.
How should you use any earplug when trigger sounds come up?
Whichever material you choose, use earplugs for short, chosen events such as a meal, a study block or a train journey, then take them out, because NHS guidance on hyperacusis advises against wearing earplugs or ear muffs all the time.
The NHS hyperacusis page notes that constant wear could make you more sensitive to noise, while short-term use may help in very noisy places. Stop straight away if you notice pain or itching. If you find yourself reaching for earplugs all day, that is worth raising with your GP.
Your GP is the starting point for an NHS referral to audiology, ENT or psychology services. The Oxford Health Specialist Psychological Interventions Clinic lists misophonia among the problems it publishes information on.
Night is a separate question. If trigger sounds follow you into the bedroom, such as a partner’s breathing, our guide to misophonia and sleep covers rest when triggers will not stop. The same foam-versus-silicone choice for a whole night is covered on our page about earplugs for sleeping.
For most trigger-sound moments, the answer to silicone vs foam is silicone: enough attenuation to make the room quieter, less of your own chewing in your head, and a pair that lasts up to 100 uses. Foam still suits loud, one-off events where you need not follow a conversation. For the full set of criteria, including fit and headphones, our guide on how to choose earplugs for misophonia walks through them.
