	===~~Sound Pressure Level~~===		===General===
	Sound pressure level (SPL) is measured in dB. The 1133 measures sound across a very wide range, with a frequency range of 100Hz to 8kHz and pressure level from 50dB to 100dB. The formula reports SPL , but the sensor is not sophisticated enough to be used as a substitute for a professional SPL Meter.		Sound pressure level (SPL) is measured in dB.

	The voltage output of the sensor can vary by up to 0.1V in a pressure-stable environment. This is especially noticeable at lower output voltages. The best way to deal with this is to average a handful of reported values.		The voltage output of the sensor can vary by up to 0.1V in a pressure-stable environment.

	===Formula Dependencies===		===Formula Dependencies===
	It is important to note that measuring ~~sound pressure levels~~ is very complex and depends on factors other than only the perceived volume. One of the major contributing factors is the frequency of the sound source. Different frequencies of a sine wave with identical amplitudes will generate very different sound pressure levels. Other factors can be the distance between the sound source and the microphone, and even the type of sound source, such as speakers. The bandpass filter of any speaker can affect the output gain at certain frequencies without any change in the volume knob of the speaker. Electrical noise in the power supplied to the sensor can affect the output. If the power supply is very noisy, this will introduce an offset in the output. It is much more noticeable when trying to measure smaller sound pressure levels due to the very small voltages of the microphone being affected much more. As a result, the previous formula is only accurate for a 1kHz pure tone. At other frequencies, there can be up to an 8dB difference between the calculated SPL and the output of a calibrated Sound Pressure Level meter.
