Threshold of discomfort
The threshold of discomfort (TD) is the sound pressure level at which a sound becomes uncomfortably loud. It is an important concept in audiology and sound engineering, as it helps to ensure that sound levels are not so high as to cause discomfort or damage to the ears.
Sone 248, the equal-loudness reference point, is closely related to the threshold of discomfort. Sone 248 is defined as the loudness of a 1000 Hz tone that is judged to be equally loud as a 248 Hz tone at 60 dB SPL. The threshold of discomfort is typically around 120 dB SPL, which is about 20 sones.
The relationship between sone 248 and the threshold of discomfort is important because it helps to ensure that sound levels are not so high as to cause discomfort or damage to the ears. For example, if a sound system is calibrated to produce a sound level of 100 dB SPL, then the perceived loudness of the sound will be about 10 sones. This is well below the threshold of discomfort, so the sound will not be uncomfortably loud.
However, if the sound system is calibrated to produce a sound level of 120 dB SPL, then the perceived loudness of the sound will be about 20 sones. This is at the threshold of discomfort, so the sound will be uncomfortably loud and may even cause damage to the ears.
Understanding the relationship between sone 248 and the threshold of discomfort is important for ensuring that sound levels are not so high as to cause discomfort or damage to the ears. This understanding is essential for audiologists, sound engineers, and anyone else who works with sound.
