Hoping to make my practice space quieter
« on: July 31, 2011, 11:53:53 PM »
Hello all-

Forgive me if this is a dumb post, as I am a new member with little acoustic experience.  My problem is this:

I am a professional trumpet player.  I rent an apartment and practice in one of the bedrooms.  The space is about 10'X11'X8'.  The floors are hardwood and the walls and ceiling are plaster.  I currently have some home made panels up (rigid insulation backed with 1" boards", and an area rug on the floor.  The problem is that when I play at a comfortably loud volume, it sounds VERY loud in the room and my ears will even ring after 30 minutes or so. 

The room I practiced in during college were smaller but quieter, and I'm wondering if I just need to carpet the room, buy some professionally made absorption panels, or what is best.  Is the problem that the noise is reverberating too much off the plaster?  As a renter, I am hesitant to pay to carpet the whole room, or to build a room within a room.   

Any help is greatly appreciated.

For your room size you will need at least 65 sqft of either pyramids or Anechoic wedges. If you are using carpet you will at least need 215 sqft. in order to notice a change in the room...
This is the starting point for absorption in a room you will need to add more if you want to improve reduction.
Here is the basic formula for figuring absorption.
LxWxH of room x 0.049 / NRC= 1 second.
NRC is the value of absorption given to products.
You can call me direct if you need further assistance.

Thanks for replying to my post.  I've actually just seen your reply today. 

In your response, you mentioned a formula.  I guess I'm a little confused by it.  What is the output of the formula supposed to tell me?  How much the sound is reflecting, the length of time the sound is reverberating, or something else? 

Thanks again for any help you can give me.

The formula will tell you how many square feet of an absorbing material you will need to have in the room before you will notice a difference.
Based on the absorption value of that material.(NRC)
