In the automotive and consumer electronics industries, sound measurement and evaluation are frequently performed to reduce noise in equipment and design desirable sounds. Until now, microphones were typically used to detect fluctuations in sound pressure, and the difference from a reference value was quantified as "sound pressure level." However, when analyzing based on "sound pressure level," the final evaluation is determined by human perception, leading to variability among personnel and making quantification and automation difficult. To evaluate this subjective auditory impression based on human sensibilities as an objective physical indicator, psychoacoustic evaluation parameters calculated using psychoacoustic technology were developed. Currently, numerous parameters have been proposed, and their use and combinations are selected depending on the sound being evaluated.
The OS-2140 sound quality evaluation pack is a package that plugs sound quality evaluation software into our time-series data analysis tool, "Oscope Professional." In addition to conventional frequency and octave analysis, it quantifies and quantifies sound using six psychoacoustic parameters: loudness, sharpness, roughness, variation intensity, AI, and tonality. By using OS-2140, you can improve the sound quality of your products, reduce inspection costs, and shorten product development time.
- "Loudness", "Sharpness", "Roughness", "Variability"
The system calculates six sound quality evaluation parameters: "AI" and "Tonality". - Multi-channel data processing (maximum 512 channel data files)
- Since you can record directly to your computer's hard drive, no special recording equipment is required.
- Smooth analysis is possible by comparing multiple files and multiple conditions.
- Timeline editing is possible with simple mouse operations.
