The Phon value is a measure of the perceived loudness of a sound. It is based on the human ear's response to sound at different frequencies. The Phon value of a sound is equal to the sound pressure level (SPL) of a 1000 Hz tone that is perceived to be equally loud.The Sone value is a measure of the subjective loudness of a sound. It is based on the human ear's response to sound at different frequencies and intensities. The Sone value of a sound is equal to the number of times that the sound is perceived to be as loud as a 1000 Hz tone at 40 dB SPL.The decibel value is a measure of the sound pressure level (SPL) of a sound. It is based on the ratio of the sound pressure to a reference sound pressure. The decibel value of a sound is equal to 20 times the logarithm (base 10) of the ratio of the sound pressure to the reference sound pressure.In this case, the two tones have the same perceived intensity, which means that they have the same Phon value. However, they have different frequencies, which means that they have different Sone values. They also have different decibel values, because the decibel value is based on the sound pressure level, which is different for the two tones.
