To reach 363 sones, we must understand the exponential relationship between dB and Sones. The formula for converting dB to Sones (for a 1 kHz tone) is approximately:

Taking the log base 2 of both sides: [ \log_2(363) \approx 8.5 ] [ \fracx - 4010 = 8.5 ] [ x = 125 \text dB SPL ]

Sone 363 is equivalent to approximately 125 decibels.

[ \textSones = 2^\left( \frac\textdB - 4010 \right) ]

Let us solve for decibels at 363 sones:
