What is sone?Sone is a unit of loudness that measures the perceived loudness of a sound relative to a 1000 Hz tone.
It is named after the German physicist Hermann von Helmholtz, who first proposed the concept in 1863. The sone scale is a logarithmic scale, which means that each step up the scale represents a doubling of perceived loudness. The sone scale is used in a variety of applications, including acoustics, audio engineering, and noise control.
The sone scale is important because it provides a way to measure the perceived loudness of sound in a way that is independent of the frequency of the sound. This makes it a valuable tool for comparing the loudness of different sounds and for assessing the impact of noise on people.
Here are some examples of sone values:
- A whisper has a sone value of about 0.001.
- Normal conversation has a sone value of about 0.5.
- A jet engine has a sone value of about 100.
The sone scale is a useful tool for understanding the perceived loudness of sound. It is used in a variety of applications, including acoustics, audio engineering, and noise control.

For example, the sone scale can be used to compare the loudness of a jet engine to the loudness of a whisper. A jet engine has a sone value of about 100, while a whisper has a sone value of about 0.001. This means that a jet engine is about 100,000 times louder than a whisper.
The sone scale is a valuable tool for understanding and measuring perceived loudness. It is used in a variety of applications, including acoustics, audio engineering, and noise control.
2. 1000 Hz tone
A 1000 Hz tone is a sound wave with a frequency of 1000 cycles per second. It is the reference tone for the sone scale, which is a measure of perceived loudness. The sone scale is based on the loudness of a 1000 Hz tone at a sound pressure level of 40 dB.
The connection between the 1000 Hz tone and the sone scale is important because it provides a way to measure and compare the loudness of different sounds. This information can be used to design quieter products, assess the impact of noise on people, and develop hearing protection devices.
For example, the sone scale can be used to compare the loudness of a jet engine to the loudness of a whisper. A jet engine has a sone value of about 100, while a whisper has a sone value of about 0.001. This means that a jet engine is about 100,000 times louder than a whisper.
The 1000 Hz tone is a valuable reference for the sone scale because it is a pure tone that is easy to generate and measure. It is also a frequency that is close to the center of the human hearing range.
The sone scale is a useful tool for understanding and measuring perceived loudness. It is used in a variety of applications, including acoustics, audio engineering, and noise control.
3. Logarithmic scale
A logarithmic scale is a scale in which the values increase by a constant factor for each step up the scale. This means that each step up the scale represents a doubling of the value. The sone scale is a logarithmic scale, which means that each step up the scale represents a doubling of perceived loudness.
The connection between the logarithmic scale and sone 436 is important because it allows us to measure and compare the loudness of different sounds in a way that is consistent with how we perceive loudness. For example, a sound that is twice as loud as another sound will have a sone value that is twice as high.
The logarithmic scale is also useful for representing a wide range of values in a compact way. For example, the sone scale can be used to represent the loudness of sounds that range from a whisper to a jet engine.
The logarithmic scale is a valuable tool for understanding and measuring perceived loudness. It is used in a variety of applications, including acoustics, audio engineering, and noise control.
4. Doubling of loudness
The sone scale is a logarithmic scale, which means that each step up the scale represents a doubling of perceived loudness. This is important because it allows us to measure and compare the loudness of different sounds in a way that is consistent with how we perceive loudness. For example, a sound that is twice as loud as another sound will have a sone value that is twice as high.
The doubling of loudness is a key component of the sone scale. It allows us to compare the loudness of sounds that are very different in intensity. For example, a whisper has a sone value of about 0.001, while a jet engine has a sone value of about 100. This means that a jet engine is about 100,000 times louder than a whisper.
The doubling of loudness is also important for understanding the impact of noise on people. Exposure to loud noise can cause hearing loss, tinnitus, and other health problems. The sone scale can be used to assess the impact of noise on people and to develop noise control measures.
The doubling of loudness is a fundamental concept in acoustics and audio engineering. It is used in a variety of applications, including sound level measurement, noise control, and audio system design.
5. Acoustics
Acoustics is the science of sound. It deals with the production, transmission, and reception of sound waves. Sone 436 is a unit of loudness that is used in acoustics to measure the perceived loudness of a sound.
- Sound waves
Sound waves are mechanical waves that travel through a medium, such as air or water. The frequency of a sound wave determines its pitch, and the amplitude of a sound wave determines its loudness.
- Loudness
Loudness is a subjective measure of the strength of a sound. It is influenced by a number of factors, including the sound's intensity, frequency, and duration. Sone 436 is a unit of loudness that is based on the perceived loudness of a 1000 Hz tone at a sound pressure level of 40 dB.
- Sound level measurement
Sound level meters are used to measure the sound pressure level of a sound. Sound pressure level is measured in decibels (dB). The sone scale can be used to convert sound pressure level measurements into loudness measurements.
- Noise control
Noise control is the practice of reducing unwanted sound. Noise control measures can be used to reduce the impact of noise on people and the environment. The sone scale can be used to assess the impact of noise on people and to develop noise control measures.
Acoustics is a complex and fascinating field of study. The sone scale is a valuable tool for understanding and measuring sound. It is used in a variety of applications, including sound level measurement, noise control, and audio system design.
