Hello,
I'm preparing for my baccalaureate this year and I'm having trouble concentrating on my work because I'm very sensitive to noise.
I've heard about NoiseGuard headphones (by Sennheiser) or Noise Cancelling (by Logitech), which supposedly emit sounds that are out of phase with external sounds so that they can no longer be heard. My goal is not to listen to calm music, but simply to have perfect silence (around 0dB!), so I bought and tested the SENNHEISER PXC 300, which didn't suit me because it has no effect on a person's voice in a neighboring room, so I am looking for a noise-canceling system much more powerful than that. I'm planning to buy the Logitech this time, but I'm afraid of getting the same result.
Does anyone know of a headset with an effective noise-canceling system for perfect silence?
Thanks in advance.

First, some small information:
- 0 dB does not exist unless you are in a space without matter. A very quiet room is around 40 dB (I don't remember the exact numbers, but it's in that range)
- The frequency range of spoken voice goes from about 200 Hz to 5000 Hz (it can be a bit lower and a bit higher)
- There are several types of hearing protection:
- non-molded earplugs
- molded earplugs
- passive headphones (no electronic components)
- active headphones (reduce constant noises like humming, but not unexpected sounds like a horn)
When you say "Can you hear people's voices when they speak next to you?" It all depends on the level they are speaking at. A person's voice typically ranges between 65-80 dB(A); your headphones (Thunder T3 - https://ecentre.audika.fr/57-bouchons-sur-mesure) attenuate by 36 dB at 8000 Hz, but only by 18.3 dB at 125 Hz (which is very low, by the way), so you will have a voice that varies from 40-55 dB(A), which is already very low (like in a recording studio)... but you might hear it if you concentrate.
As mentioned, you can use two protection systems: plugs + headphones, but be careful, you won’t have 30 + 30 = 60 dB of attenuation. It's more complicated than that.
As for simulating being deaf... it's a bit complicated because this isolation system only isolates sounds coming from the outer ear (tympanic membrane) and not from the inner ear, not to mention the discomfort caused by the headphones...
So that's it for your information... but if it's for an experience, it's better not to use the plugs for hygiene reasons and their poor quality (for non-molded plugs).

There are also anti-barking collars for dogs, which helps avoid wearing headphones but also reduces annoyance towards neighbors.

For your information, 0dB exists and corresponds to a pressure increase of 20x10^-6 Pascal. The decibel scale was created by acousticians to best represent the sound sensation perceived by the brain, and it starts (at 0dB) with the threshold of audibility of the human ear (and not with absolute silence, which is only obtained in the absence of matter). However, it can be agreed that it is very difficult to achieve (except in an acoustic laboratory).
