Option 1 - living room. * pro: larger room* con: too much echo from all the stuff in living room
@lostinidlewonder, we noticed the fuzzy vibration echo from things like lamp (metal parts) or window (glasses). Spoke to tuner, he suggests keep piano certain angle away from those items.
That is more likely to be sympathetic vibration than echo. It can happen in any size room. Best thing to do is to adjust the offending item that is vibrating, such as the said lamp.
A larger room is better for a grand especially when you open it up. Grands can easily become too noisy in smaller rooms and the lid needs to be closed and you may even need to cover the piano while playing. It is nice to play for others with the grand opened up and have a room that is large enough to deal with the big sounds that come out of it. Many people have grands in rooms that are far too small, the grand just becomes more of a decorative piece than something that improves the sound in the room you are playing in. One of my students has a 7'4" grand in a small room and it's bloody noisy, not good at all, we put large pieces of felt inside the piano to dampen it but it's still bloody loud lol.
Then again, some people seem to have a big piano working in a small room. Josh Wright's studio has two grands in it, one of them a 9 foot concert grand. From his videos, it seems like the room is somewhere in the range of a large bedroom in size. He also likes to play with lids fully open.
I have noticed this is a problem with some students of mine who have performed on larger stages for the first time. Some of my students practice on pianos which are in very small rooms so they never really understand what it is like to project the sound into larger rooms. There is more room to move, your volume levels do not need to be so subtle as you need to do it in enclosed spaces. Because of this when they play on stage for the first time sound too quiet because they can hear the piano in front of them but are unaware of how it is projecting beyond the space immediately infront of them. It is always advantageous then to have a grand piano in a larger space so you can experience over time how its sound projects through the space and not treat the piano merely as a speaker infront of you but rather an entity which surrounds the air around you.
It's important to be able to soundproof and dampen the sound in the room you use. Pianos are capable of producing sound levels that are dangerous to your hearing long-term if you don't take precautions.
I did not need to actually soundproof my piano room, snd I know of many pianists who have not needed it, either. For me, soft furnishing did the trick: a thick tug pad underneath a large rug, chairs, pillows, drapes. Experiment to see what your actual room needs.
I once used a decibel meter to measure what sounds levels my baby grand produced at home. With a closed lid I could still push peaks to 90-100 dB without too much effort. For reference, sounds below 70 dB are generally safe.
The NIOSH Recommended Exposure Limit (REL) for occupational noise exposure is 85 decibels, A-weighted, as an 8-hour time-weighted average (85 dBA as an 8-hr TWA) using a 3-dB exchange rate. Exposures at or above this level are considered hazardous.
Now 85 dBA here doesn't mean 85 dB at peak. It's a total exposure, which is averaged over time, and "occupational" means 5 days a week every week. You don't play ff all the time, and I don't think you practice 8 hours a day (I certainly don't). Of course we are all different, and my ears do start ringing when I play ff for some time even with a closed lid. They didn't when I was young, and they may ring now without piano too Is it hazardous? Maybe. Also DB meters (well, expensive ones) have "fast" and "slow" mode. You need "slow" mode to average (usually over 3 sec).
If you read online about the dB of a piano, an often cited number is that piano practice is typically between 60-70dB.
Yeah, that sounds totally wrong. I used a cheap sound meter BAFX3370 (so take it with a grain of salt), which I used to calibrate REW app at 1kHz, which in turn I used to measure an equivalent dose with a calibrated mic. So playing in the range of p-f with a closed lid gives me ~82dB (give or take), after opening the lid it goes up to ~85dB. If I start pounding hard it easily goes up to ~90dB and further. But still, according to NIOSH even 88dB gives me ~4 hours a day without any serious damage (each +3dB cuts time approximately in half, for an average guy of course). I have Yamaha 5'8", but with a foam under the belly to cut hardwood floor reflections. Anyway, it's not even close to 60-70dB, yet within NIOSH limits. So when I want to enjoy my playing I'm opening the lid, at least partially, but when I practice, especially something like scales, I keep the lid closed.
