Page 5: Measuring Sound
The calibration process includes the microphone, preamplifier and sound level meter. Any change in this measurement chain will require a new calibration certificate. SKC offers a complete calibration service offering a NIST calibration that can be supplied with or without a test report. -
Page 6: Reflections
The SoundCHEK Essential will register an overload if the noise level exceeds the linear operating range of the range selected by 0.5 dB, so it is advisable to determine if an overload will occur on the selected range before measuring. In such cases, you will need to select a higher range to accommodate the higher peak levels. - Page 7 A Weighting The SPL is filtered in such a manner as to reflect the hearing response of a human ear. The signal is progressively attenuated at the higher and lower ends of the audible frequency range but much more attenuation occurs at the lower end of the audible frequency range. Generally, this is the most commonly used frequency weighting.

Page 8: Overload And Under Range
The SoundCHEK Essential will display these events as “OL” (overload) and “UR” (under range) in bold red lettering or inside a red box. They will always be displayed in the same place on each measurement screen. - Page 9 Overload Under Range skcinc.com Form 37177 Rev 200910 Page 9...
