UTPKSP7BL is a high-precision and low-noise differential sound-pressure level (L SPL) meter designed for acoustic and psychoacoustic applications. It is used to measure acoustic signals with a frequency range from 20 Hz to 20 kHz, along with the sound pressure levels in the corresponding frequency ranges.

The UTPKSP7BL is based on a two-channel voltage-measuring device and utilizes two microphones (either side-fired, spaced omnidirectional or other anti-directional microphone formats) so that the UTPKSP7BL can accurately measure the differential sound pressure between two acoustic signals, in order to distinguish them from one another. The device is calibrated for broadband sound sources and is capable of accurately measuring the SPL of each source, independently or simultaneously. The sensitivity of the UTPKSP7BL is typically 6 dBV, and a maximum differential measurement of 105 dBA is supported.

One of the main applications of the UTPKSP7BL is in sound engineering, where it is used to determine the dynamic range of sound sources, such as loudspeakers, microphones and amplifiers. It is also used in psychoacoustics, where the accuracy and range of the device are crucial in obtaining accurate results. In psychoacoustics, the UTPKSP7BL is used to measure how the human ear perceives and responds to acoustic signals.

The UTPKSP7BL uses a unique accelerated distortion correction technique (ADC) to accurately measure the signal. This technique combines the effects of voltage-controlled and fixed-frequency filters with the distortion from the microphone/amplifier combination to produce the desired results. It also uses a frequency response analysis technique to measure the inputs with an accuracy of about 0.5 dB per decade of frequency.

The working principle behind the UTPKSP7BL is simple yet sophisticated. It measures the SPL difference between two sound sources, and then calculates the average SPL within that range. This average is then used to establish the noise floor for the device, which is then used to calculate the frequency response and the distortions caused. It also measures the phase response of the microphone/amplifier combination.

Overall, the UTPKSP7BL is a highly accurate and reliable device that is used in many fields including sound engineering and psychoacoustics. It has the ability to measure the SPL difference between two signals, and can accurately and quickly calculate the average SPL within that range. The device also uses a unique accelerated distortion correction technique (ADC) to accurately measure the signal. The simplicity and accuracy of the UTPKSP7BL make it an essential tool for many sound engineers and psychoacoustic researchers.
