These FE cars are MUCH quieter than their F1 cousins.
- rcxdude 12y agoWell, in terms of sound energy, but our hearing is also logarithmic, so 140dB will sound about twice as loud.
- zik 12y ago> an increase of 10db SPL is perceived to be approximately twice as loud From http://trace.wisc.edu/docs/2004-About-dB/ http://trace.wisc.edu/docs/2004-About-dB/ So it's really 2^6 = 64x as loud, perceptually.
