What is That Rattling!!!

I’m sure we’ve all been there.  Driving down the road, whether it is to work, the store, or anywhere really, and then you notice it.  It may be faint at first, but as time goes on, and you continue to drive, it gets more and more annoying.  I’m of course referring to vehicle BSR (buzz, squeak, and rattle) issues.  They’re probably more responsible for people smacking their dashboard than road rage (at least they are with me).  There really isn’t much of anything more harmful to the quality image of a vehicle than frequent or sporadic BSRs. This is especially true when the noise is so obvious and constant which makes it such an important aspect of testing.

MGA has been performing BSR testing for many years, and this experience has helped us develop a keen ear for determining what sounds might be considered a problem, and what sounds would not.  However there are times, more often than not, when subjective evaluations are not enough to make a judgment.  With these situations a “quiet room”, with calibrated microphones specifically built to record the most sensitive sounds, is used.  The data measured from this system can be presented in various units such as decibels (dB) or sones.  The ability to compare exact values as opposed to listening to differences with the human ear is incredibly helpful with comparison studies and development.
