TL;DR - FMA L/XL sized helmets tend to fit big heads better than others, from personal experience (62cm bonce) the FMA Exfil Bump (Team Wendy knock off) and the FMA PJ style FAST both fit well with plenty of space, others have suggested that the FMA AirFrame is particularly roomy. You may have to remove some of the pads to fit your head properly. Quick note - different shells have a different head shape so one size in an OpsCore style won't necessarily fit the same as the same size in a Team Wendy style. I find the Ops Core ones are too round for my head for example.

Also - I will caveat this by saying that I was told all of this in the past and I never paid attention to it either.

Seriously - protect your hearing while you can. You WILL miss it when you lose it. I have hearing loss and tinnitus caused by noise damage (both industrial and music related - I used to play in a death metal band) and it SUCKS.

Pictures?

Fair, the combination of earplugs and earmuffs is often more than just the sum of the two devices though: https://multimedia.3m.com/mws/media/893191O/earlog-13.pdf?fn=EARLog 13.pdf That shows that the NRR of combined devices can be as much as 50dB. The other thing to consider is situational awareness. If you're wearing ear defenders AND ear plugs to deal with a potential flashbang then you will NOT hear anything else. Attenuation due to distance is governed by an inverse square law which equates to 6dB per doubling of distance. Something that is 120dB at 10m will be 146dB at 0.5m (calculator here: https://www.wkcgroup.com/tools-room/inverse-square-law-sound-calculator/) IN OPEN SPACE! As for the Thunder B - while I can find references to "up to 130dB" I don't see anywhere that it says what distance that is measured at?

Good point very well presented. The main danger will be indoor events, I don't know of any that would actually be covered by their insurance (assuming you're in the UK) for anything over a MK5 indoors so that would immediately drop you to around 120dB. Personally I've never had an issue with anything in the UK while wearing active hearing protection (Earmor M32s and Howard Leight Impact Sports) so I would think you'd be fine. If your local site is allowing TAG grenades like the M67 indoors then I'd be looking for somewhere else to play. Also important to know is that your dB calculation is a bit off:

It's highly unlikely anyone has done this due to the spectacular array of confounding variables. For example - EG say their MK5s are 120dB at 10m. Obviously the closer you get the louder it is and it's NOT a linear progression. Once you put that measurement into an enclosed space you change the way that the pressure waves behave so a small space can make the listener perceive a higher noise level than the same distance in the open. Add to that the material that any room is made from will also affect the way that the pressure waves behave and you have an enormous range of measurements to try and deal with. As for manufacturers "often claiming 140-150dB" I don't know that I've ever seen any pyro that is covered by site insurance that goes that high with the exception of things like the TAG grenades. More to the point, why do you want/need to know?

...and they published it themselves? Talk about shooting yourself in the foot!

After I signed the petition the very next one up was to make Middlewick Ranges up the road into an SSSI to stop it getting built on. Sounds like the council are having a fun old time of it!

They're saying the site is protected because it's an SSSI but if you look up SSSIs in the area it's only the reservoir up the road, the boundary of which doesn't actually appear to cover the airsoft site. If the site was in the bounds of the SSSI then it would never have gotten permission to run! Signed by the way.

It was only a couple of weeks ago and obviously stuck in his mind. It's not that deep.

Thanks for that man, I'm sure the bike I have is fine (although it's getting a bit worn out). I have a tendency with all my hobbies though to look at what I have, identify an excuse a perfectly valid reason why it's not good enough and then go buy a new one. I've actually been looking at a Rockhopper Comp but a lot of my confusion was trying to work out what the current equivalents to my existing groupset is. To get the level of kit that has developed on my bike with a steel frame it looks like a £2k+ spend though so that ain't happening!

The new Gate Asters can do decock now too.
