SUMMARY
The discussion centers on the relationship between amplitude and perceived loudness, confirming that while doubling amplitude results in a doubling of loudness, the human ear perceives loudness on a logarithmic scale. This means that different frequencies are interpreted variably, necessitating the use of different weighting functions such as dBA and dBC to accurately represent perceived loudness across various sound frequencies.
PREREQUISITES
- Understanding of logarithmic scales in sound perception
