MC2024 Day 3 Vid Selič 🔈Mastering Advanced Acoustics Analysis
2🔺Dewesoft #MC2024 Day 3 Vid Selič 🔈Mastering Advanced Acoustics Analysis. It was an in-depth #session where Vid Selič, Head of the Application Center at DEWESoft, took us through the complexities of #Advanced #Acoustics #Analysis focusing on #specialized #microphones and #probes to conduct #precise acoustic #measurements in a free field environment. https://youtu.be/XvsPhQDLCak
Understanding Free Field Requirements:
For accurate acoustic analysis, a proper #setup is #crucial. This session explains the necessity of conducting measurements in an #anechoic #chamber or an outdoor area devoid of vertical reflective surfaces within a 50-meter radius, adhering to #ISO3744 and #ISO3745 standards. These #standards outline methods to determine sound #power #levels using #engineering approaches in essentially free fields over a reflecting plane, and precision methods for anechoic and hemi-anechoic rooms.
Exploring Sound Intensity:
We delved into the concept of sound intensity, defined as the time-averaged rate of energy flow (power) carried by sound waves per unit area, perpendicular to that area. This vector quantity not only measures the magnitude but also the direction of sound energy flow, crucial for accurate analysis.
Measuring Techniques:
We learned how sound intensity is measured through the time-averaged product of instantaneous pressure and corresponding particle velocity at the same point. In the demo the practical application of these measurements using the latest acoustic technology.
Noise Source Identification:
The session also covered noise source identification techniques, utilizing the directionality of sound intensity.
Sound Quality Assessment:
Additionally, we explored the subjective aspects of sound, such as sound quality, which encapsulates how sound is perceived in terms of tonality and frequency masking. Discussions about how two sources emitting the same sound energy can be perceived differently emphasize that quieter isn't always necessarily better.
This detailed session was designed for #professionals looking to enhance their understanding of acoustics in various engineering fields, offering both theoretical knowledge and practical application insights.
