Sound Quality Evaluation Function for O-Solution
OS-0525
-
The sounds generated from the equipment are mainly measured by evaluation based on general analysis such as sound pressure level, FFT analysis and 1/3 Octave analysis. However, since those analysis don’t take into consideration the human hearing characteristics enough, sounds with even the same analysis result may give different impression.When a human listens to a sound, various sensations such as loudness, sharpness, and roughness occur.

Decibel Meters
-
A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed. Here at PCE Instruments, we offer two types or classes assigned to decibel meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 decibel meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used.

SPL Calibrator -124 dBSPL @ 1 kHz
511ES124
-
The 511ES124 is designed to provide 124 dBSPL at 1 kHz to meet the needs of the low sensitivity microphones found in many high SPL measurement applications. The microphones used in Car Stereo competitions like dB Drag racing, IASCA, and USAC have had their sensitivities reduced to the point where 94 dBSPL may no longer be adequate for calibration.

Sound Level Meters
-
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.
