A proper analysis is key
A proper analysis is key when comparing different noises to analyze which one is louder. But what is the best analysis for this acoustic test application?
In this tutorial we introduce two different analyses:
• Sound pressure level dB(A)
• Loudness sone
We compare the performance with respect to the following aspects:
• Scaling 01:20
• Frequency Weighting (A B C D) 03:43
• Time Response 08:25
• Masking Effect 12:04
• Frequency Resolution 12:30
• Level of detail 15:31
• Time Resolution 17:21
• Overall Summation 20:29
All analyses are presented wihtin the acoustic analysis software ArtemiS SUITE, which offers these flexible options.
