Sound Monitoring & Matching API based on Sound Similarity Measurement (for Sound Recognition Projects)
-
Sound recognition is one of the main application areas of artificial intelligence. Various sound recognition techniques exist and can be used for recognizing speeches, music, environmental sounds, animal sounds, air-borne or structure-borne machine sounds, etc. These techniques contain in common signal pre-processing, feature extraction and feature matching / classification algorithms from a general perspective. However, they differ in implementation in different applications. For example, there are a few good automatic speech recognition software products and APIs, however, they just cannot be used directly in animal sound classifications.

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.

PeakTech Prüf- und Messtechnik GmbH
For sound level measurements in extreme conditions, at high altitudes or high demands on the accuracy of the measurement results, sound level meters should be checked prior to the measurement with a sound level calibrator. Also for calibration and verification of microphones in audio technology, you need a sound level calibrator, which is designed to produce several sound pressure levels at a fixed frequency characteristic. This calibrator has two switchable calibration steps.
