WebPerceived noise reduction: 5.5 phons (dB SPL at 1 kHz) After soundproofing, acousticLoudness shows the perception of the engine noise is approximately 5.5 dB quieter. Human perception of sound is limited at very low frequencies, where most of the engine noise is. The soundproofing is more effective at higher frequencies.
