Hey Guys,
I have the following question: A friend of mine is planning to do some sound proofing at his place because he is too bothered by his neighbors. The company he contacted told him that the house he lives in will let them perform insulation that is about 10cm thick, which will correspond to a sound reduction of approximately 5 decibels. Considering there are lots of musicians here, I thought someone might have an idea weather a sound reduction of 5db is good enough or not..

Any thoughts would be very welcome.
Thanks,
O.

Instead of writting a book to answer You precisely I'll only try to simply answer the question smile.gif Yes - 5db is a big value.

Make simple experiment. Bring or borrow a P.A Mixer - it has db meters and scale next to each fader. Play some music at different volumes (different main output faders positions in the mixer). Let's say You plugged CD to the 1 and 2 channel of that mixer. Set the track 1 and track 2 faders to -5 dB position slowly push them up to 0 dB.

You will have the best answer about what is 5 dB and how You feel the difference of 5dB in different volume ranges like:

regular music rehearsal volume, loud music listening, full live band rehearsal.


You can do the same experiment with a laptop plugged to the P.A or very loud hi-fi. Play a song You know through any DAW and change the track volume between -5dB and 0 dB.

Now words will describe it better than such a simple test smile.gif))

You need more information really to answer the question. Whether a 5dB reduction is sufficient depends on the noise level measured at the boundary of the property using a dB meter on c weighting and what the local noise requirements/laws are.
