Everything you need to know about Buzz, Squeak and Rattle Noise testing
Introduction
Buzz, squeak, and
rattle are simply noises that are normally produced by parts that are installed
in a way that they create annoying sounds. Therefore, the three are caused by
relative motion emanating from installed parts. These parts interact hence
producing the annoying noise. Such noise is sometimes being produced only at a
specific environmental condition.
Buzz
Buzz is a type of noise
that emanates from motion caused by moving installed parts. This specifically
emanates from the part of the structure itself.
Squeak
This is also a kind of
noise that can irritate too. This kind of noise is caused by friction between
the two installed parts. This can be eliminated through bsr noise testing lab
Rattle
This is also a kind of
noise that can be annoying and it always emanates from the impact parts and
friction.
Buzz, squeak, and
Rattle
The three are sounds
that can cause extreme annoyance for many people. The three make many people
complain all the time. There is no single person who loves hoe Buzz, squeak,
and Rattle sound. Even if the sound is not too much, it simply becomes an
annoyance. Those vehicles without buzz, squeaks, and rattle are always
associated with high quality. That is why vehicle industries need to achieve
quality. This can be done through the noise
and vibration testing
What are the acoustic
test types that are within buzz, squeak, and rattle?
The silent shaker- This
is the first test that you should know of. This is the kind of test that is
normally performed in an NVH ring normally with a silent shaker. In this case,
the excitation profile for the part being tested is always used. The loudness
is then analyzed. This kind of testing is always suitable for early
verification.
The test track
The next step of
evaluation is the test track through noise
bsr testing. This is always done immediately the vehicle prototype is
available. This is a type of subjective evaluation and it is always supported
by a microphone and the combination of headphones as well. The tests are
normally repeated especially after durability testing just to ensure minimum
degradation.# Everythingyou need to know about Buzz, Squeak and Rattle Noise testing
