Products for Sound and Vibration Monitoring
Leonhard offers a solution based on a new model, APPA,
for auditory perception that is unique for sound and vibration
(S&V) monitoring. The new model analyse the dynamic behaviour of
signals such as oscillations and dynamic energy. The heart of the
solution is the software packet that makes all the calculations, and
makes it easy for other applications to grasp the results.
- APPA is an effective and reliable way to S&V monitoring
- APPA gives exact and detailed information about the sound picture
APPA reflect the way the ear perceives sound.
APPA is based on the following analyses
- Oscillation analysis
- Dynamic energy analysis
Many companies make acoustic monitoring and quality control of their product
- Either by stroking the item and listening to the sound response
- Or by listening to machinery with moving parts
- APPA is outstanding to measure that objectively
- APPA is very suitable for measuring distortion
The monitoring of parts is based on a Sound Picture Profile (SPP)
- Set up a SPP reference for acceptance based on an analysis of a batch of good and bad parts
- Sorting of produced parts by means of acoustic monitoring based on the reference
- Simple pass/reject criteria is used and no need for neural network or other artificial intelligence are used
