Recording overall system noise.
Use the AccuTrak
®
to record sound levels of compressor noise, fan vibration, fan
belts, motors, and even noisy ducts.
The overall sound level of a system can be recorded and compared to previous
and future readings. If a system owner is complaining about increased noise
coming from certain equipment, this can be verified if previous AccuTrak
®
readings were taken.
Although the AccuTrak
®
will only record the ultrasonic range of a noisy system,
this part of the sound will increase in proportion to the sonic part the customer is
hearing and complaining about.
Taking a baseline reading.
When taking a reading of overall noise level, begin by reducing the sensitivity
until the bargraph reads slightly less than 1/2, (approximately 6). This will give
you room on the display for future readings.
IMPORTANT:
Record the sensitivity and volume setting, the numeric level
reading on the display (E.), and the position from which the reading was taken.
This will be your baseline for future tests.
