I'm new to this forum.. new to struggling with acoustic issues and generally likely to be VERY green - so go easy with me and if I'm breeching any etiquette then sorry, let me know how and I'll take corrective action.

I realise that strictly speaking this may be a little outside the experience of many of you guys and is approaching acoustics from a slightly different perspective - but that being said - someone on a Piano forum suggested that asking you guys (who might have good ideas about acoustic treatments) for assistance might really help me out - so here goes:

I just bought a new piano (yay!) - Its nothing special, no 9ft beast or anything - just an entry level baby grand. Its replacing a frankly inadaquate 10yr old Roland digital and in the showroom environment sounded great.

Getting it home however, I'm struck by how harsh the sound is. To start off with the bass was *very* soggy and hard to hear, but then I re-positioned the piano at an angle across the corner and that improved dramatically. The overall balance isnt too bad now - but the noise levels are uncomfortable.

A quick think about the room and its clear its a VERY live room. Apart from the rug beneath the piano theres nothing but hard surfaces, hardwood floor and a lot of full length glass.

Unfortunately I'm constrained by a huge WAF factor here and any improvements have to be asthetically succesful as well as acoustically valid. - I'm also trying to work on a pretty tight budget.

I considered looking for 4' x 2' acoustic panels to hang on walls (ceiling too?) from somewhere like acoustimac.com (US$50) - but the cost of shipping to Australia makes them prohibitive and the cost of sourcing a local equivalent is even sillier (AU$130+?).
I'm sure it might be possible to do a DIY construction job to help me here - and although I'm no expert in woodwork it surely cant be that hard to nail together 4 bits of timber to make a frame, stuff in some special foam and staple some cloth over it?

Before I embark on any ambitious construction - do any of you have any ideas that might help confirm that this is the right thing to do?

I'm not looking to try and make the room into a soundproof studio - I just want to be able to play it without cringing and without everyone else in the vicinity running out the house yelling "ITS TOO LOUD!!!!"

Any suggestions would be welcome.

The Room:
==============
Its an open plan living space 4m x 5.5m with low(ish) ceilings (2.4m) - and opens out into a kitchen area on one side and a study on the other (seperated by an internal bifold door).
Pretty much all 4m behind the piano is full length windows or glass doors with just vertical blinds - no soft curtains.
...as soon as I work out how - I'll add some pictures!
 
The picture upload function is broken - don't beat yer head against that wall. You could open an account at photobucket and link them.

Sounds like a lot of piano in not much room. Making 2x4x 2 or 4 inch absorbers is relatively easy but I'm not sure how they will go with the decor. Maybe you could stick 'em in a closet when you're not playing and just lean them up against the glass when you are.

Check out John Sayers' site: John Sayers' Recording Studio Design Forum • Index page That is a dedicated acoustics and studio building forum and I'll bet you'll get loads of help.

Good luck. Come back and let us know how you made out.

photobucket pictures will be added as soon as I have 5 posts to my name and am allowed to do so!
 
seems like an odd requirement to enforce this kind of spam posting...
 
The Recording Manual

Check out the links on the right-hand side of the page for info about building bass traps and absorbers. Also, check out the Forum. Tons of useful info in there about room treatments.

You want to treat the room to get RT-60 times below about a half-second across the audio spectrum for best results.

I've built stuff based on Sayers' designs and they work. You'll need to find a source for Knauf or Corning soundboard or rock wool.

What are the room dimensions???
 
sorry - links fixed... :)

as stated above room dimensions are:

Its an open plan living space 4m x 5.5m with low(ish) ceilings (2.4m) -
...and opens out into a kitchen area (3m x 2.5m? ish with kitcheen cabinets) on one side (seperated by bench height wall)
....and a study (3.5m x 2.8m?) on the other (seperated by an internal bifold door).

I really don't know much about pianos or their acoustic footprint or radiation pattern but seeing as how you don't have much on the walls you could make acoustic panels look just fine in there. Get the woman to choose the colors. A cloud would be good as well maybe but again how do pianos throw the sound?
