Dear Scientist (?),

     I'm trying to test out the effectiveness of different kinds of ear plugs 
against different kinds of sounds for my school science fair project.  I was 
planning on using a sound-level meter inside either a wooden box or a manniquen 
head, and putting the ear plugs on both sides of the head, and using the meter 
to test out the sound inside the head.  Only problem being that sound-level 
meters go for about $650. Do you know of any way i could either get access to a 
sound-level meter or something that i could use instead of a sound level meter?  
I'd appreciate any help you could offer.
