dB(A) or loudness - best analysis for my NVH task

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.
