If your bass player gives advice on how to better soundproof the garage or basement in which your band practices, kindly let him know there is a big difference between soundproofing a room and acoustic treatment. While your parents would prefer you soundproof the room your band practices, you want acoustic room treatment. Grab your bass player and have him read why.
In essence, soundproofing is reducing the sound pressure between the source of the sound and the actual pressure of the sound. What we are trying so desperately to say is soundproofing means you are trying to stop sound from leaking out of the room. Which is why you see pillows and foam taped over windows and doors, to keep that sneaky sound from escaping and wreaking havoc with the neighbors. And try as you will, it is all too difficult a task to accomplish without a huge investment. That is, it takes more than a pillow on the window to soundproof a room. Yet, people still keep trying.
On the other hand, acoustic treatment is a more sensitive subject that involves a whole lot of science, which is why you should pay more attention in these types of classes. The goal of acoustic treatment is not to prevent sound from escaping the garage or room you are utilizing, but rather to manage the sound generated inside the room. This makes a whole lot more sense when your band is attempting to create a clean sound. That is ultimately what you want, a clean sound without all the unwanted noise. Acoustic treatment changes the quality of the room from a listener's standpoint. So when the bass player’s girlfriend, Becky, listens in on a practice, she hears a better quality sound.
We’ll get into more details about sound treatment at a later date. But when considering acoustic treatment, think about acoustic panels, bass traps and sound diffusers. We’ll catch up with your later.
