Sound Power Solution
-
The Sound Power Solution is part of the family of solutions proposed by OROS for Acoustic applications. This Solution allows to measure Sound Power based on the measurement of sound pressure levels at microphone positions around a source under test. Thus, the Sound Power Solution is complementary of the Sound Intensity Solution that is based on the measurement of the sound intensity as recommended by ISO 9614. Using the OROS Solution, based on a task dedicated interface that guides the user step by step, Sound Power is measured in an easy and efficient way.?

BK3011C
-
In keeping with our goal of constant improvement, we have upgraded our BK3011 MEMS mic tester! The BK3011C is more modular, easier to connect and with the new Test Shop upgrade, easier to use. But the basic features are still the same. Then BK3011C enables you to check mic characteristices over a frequency range using a stable, constant SPL sweep. It still produces both graphs and numerical data but now will automatically classify both PASSing and FAILing DUT's so you can keep track of quality issues and trends.

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.

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.

Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.
