Sound Level Calibrators
-
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.

Understanding TEM, TE, and TM Waveguide Modes
-
Energy can propagate through a medium or through what is currently believed to be a vacuum. Propagation modes vary depending upon the type of energy and the nature of the medium.Electromagnetic energy is transmitted in waves. Like sound, it may propagate equally in all directions, the wave energy radiating in concentric shells corresponding to amplitude. Or it may be directional, focused to form a tight beam.View more Understanding TEM, TE, and TM Waveguide Modes

Vibration Meters
-
A vibration meter is used in manufacturing for machine condition monitoring, product testing and quality assurance. Many machine maintenance technicians use vibration meter devices in tandem with sound level meters to analyze frequency. A vibration meter also can be used in civil engineering to measure the vibration of structures such as buildings, roads and bridges. In addition, specialized vibration meter devices can be used to measure the vibration of the human body. Any vibration meter will measure one or more of the following parameters: vibration acceleration, vibration velocity (speed) and / or vibration displacement.A vibration meter is typically a portable device with a memory for storing measurements. Most vibration meter models feature a built-in data logger for collecting and recording vibration measurement data over time. In this way, vibration measurement data can be acquired with great precision.

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.
