Volume

I'm jealous - I've just been told to turn the volume down 

HI Chris .... same (from the previous neighbours!) hence the sound proofing!

Bang bang ..I'm trying to get to f*****g sleep.

Question: are you talking about genuine sound proofing rather than (or in addition to) acoustic treatment? If sound proofing, may I ask what materials and soundproof system you chose? I may need to be doing this myself sometime soon.

And if you also adopted acoustic treatments Can you share what you chose for those too?

Frank.

Great stuff, Pete. and I thought you could not improve on that great man cave of yours. Post some pics when you have time. Have fun! 

Hi Frank / Good to hear from you Tony!

Yes properly soundproofed and I'll do a full disclosure for you Frank, its not acoustic treatment. The door is 150mm thick and I have to have fresh air pumped in otherwise I'd not wake up when I fall asleep during extensive sessions. I had a professional  company do the the work who work on recording studios so they knew what was required

Ah, thanks for that. Wow, well and truly sealed then, which I guess is the only way to genuinely soundproof a volume of space. Thanks for the feedback.

Frank.

Interesting.

Do you have any sort of alarm if the pump fails.

Thinking of a faulty gas appliance without a CO detector type of situation !

Whilst I'm all for good sound quality and sound proofing the thought of suffocating whilst listening doesn't appeal to me.  You're a brave man!

Got a CO detector alarm and a flashing red light so all OK gents - when I fall asleep the music stops!

N16SPS,

Great stuff.Your also cutting ambient noise out of your listening room as well as being very neighbour considerate ( if you have them )  maybe that's why our systems sound good at night is the lack of ambient noise,not to mention less draw on the national grid.

I thought I'd heard it all in all things bizarre in audiophilia. You must have some incredible bass absorption in your sound proofed room.

To the OP, at 12 O'Clock just be sure that a year from now your are not posting on one the hearing loss threads on the forum.

I agree with Feeling_Zen.  Please get an accurate SPL meter (and don't just rely on a SPL app for your phone - they're not accurate), and check your levels.

It's very easy to permanently damage your hearing with high quality audio systems as they can exceed safe pressure levels without significant distortion.

Wow! Volume control at 12 o'clock. That must be seriously loud.  

Thanks for the advice Huge, I don't have the volume as high as mentioned last night, only occasionally. The think about the soundproofing is, that as mentioned above, it cuts outside noise out so the music is 'louder' at a quieter volume. Blasting it out on the occasion makes it sound more like gig.

Cheers

What is your system, BTW? I don't think I've ever gone higher than 10 o'clock, and that was with vinyl!

 

I was just thinking the same thing, Mine is uncomfortable at 9 O'clock on most things and unbearable at 10 O'clock on everything else and I think I play fairly loud.

My LP12 is out of action as I'm waiting for a new cart, the source last night was a 555 played through 552 with active Ovator S-600. It was pretty loud, and as stated above I wouldn't be able to listen at that volume for long periods.

... perhaps I'm already deaf then!

Alba it depends  what your listening too, Steely Dan doesn't compare to Motorhead, so is more bearable at volume.

This is the spec. for the soundproofing for Frank and anyone interested:

Ceiling - Suspended with a 200mm void filled with RS60 Acoustic Mineral Wool (Had to dig out the floor to reclaim height that was lost) Resilient bars to isolate from new joists then new layer of 19mm sound plank plasterboard, all edges sealed with acoustic / fire rated sealant, more acoustic wool the second layer 12.5mm sound shield plasterboard with KarmaPlus membrane.

Walls: 2x4 wood/metal structure built in front of walls, void created filled with 200mm acoustic mineral wool, in front of this 5kg acoustic membrane installed onto which resilient bars are attached. Again 19mm soundplank plasterboard again sealed. 2nd layer of M20 rubber panels  installed and again sealed. 3rd layer of 12.5mm soundblock plasterboard.

Floor: Dug out 1M then laid 300mm concrete over which laid triple barrier matt (bit like very thick rubber) again sealed over which wood floor was laid.

All electrics / sockets light are not recessed  but sit proud of the wall.

The door was the biggest challenge as I had to buy a reinforced steel door filled with various acoustic materials that comes with it's own frame. The profile looks like three small steps with acoustic rubber that fits tightly against the frame. A huge door handle is pushed upwards to force the door into the frame.

All in all it's a box within a box without air, hence the fresh air supply that's pumped into the room.

There you go!

Hi Pete,

Thank you for posting the way you describe your new listing room sound intriguing and so . Like Tony would love to see some pictures.... Please

If you stand close to one speaker you may try to damage one of your ears. In the same way I managed having spent many years next to a drum kit in rehearsals and gigs

Have fun and enjoy the room!

+3!

Enjoy your new found volume Pete, I've always got my eye out for when my next door neighbours are out so I can crank it up. Must be nice not to have the occasional thought that you got it wrong and actually they aren't out after all!

No doubt you've extensively treated the exterior boundaries of your room with attention to minimizing the adjacent sound transmission from within. I'm more interested in how you've treated the interior of the effectively sealed box. Anything to share there?
