Question: Using loudness contours ISO 226, 2003, which of the two frequencies is loudness growth greater for: 50 dB SPL tone at 125 Hz or a 40 dB SPL tone at 1000 Hz? Explain
your answer The loudness growth is greater for the 50 dB SPL tone at 125 Hz. This is because the reference sound pressure level used to define the loudness contours is applied to the 1 kHz frequency, and this reference sound pressure is relatively greater than the sound pressure at lower frequencies. This means that a lower sound pressure is required for 50 Hz frequencies relative to 1 kHz frequencies for the same loudness level. Therefore, the 50 dB SPL tone at 125 Hz will have a greater loudness growth than the 40 dB SPL tone at 1000 Hz.
