What is sone 080?
Sone 080 is a standard reference level for loudness used in audio engineering and psychoacoustics. It is defined as the loudness of a 1 kHz pure tone that is judged to be equally loud as a broadband noise with an equal power spectral density. The sone is a subjective unit of loudness, and it is not directly related to any physical measure of sound pressure or power.
The sone scale is used to measure the loudness of sounds in a variety of applications, including hearing aid fitting, noise control, and product design. It is also used in research on the perception of sound.

2. Loudness
Loudness is a measure of the strength of a sound. It is determined by the amplitude of the sound wave, which is the height of the wave from its baseline. The louder the sound, the greater the amplitude of the wave.
- Subjective perception: Loudness is a subjective perception, meaning that it is experienced differently by different people. What one person finds loud, another person may find quiet. This is because loudness is affected by a number of factors, including the individual's hearing sensitivity, the frequency of the sound, and the duration of the sound.
- Measurement: Loudness can be measured using a sound level meter. Sound level meters measure the sound pressure level (SPL) of a sound, which is the amount of sound energy per unit area. The SPL is measured in decibels (dB).
- Effects: Loudness can have a number of effects on people, including:
- Hearing loss: Exposure to loud sounds can damage the hearing, leading to hearing loss.
- Tinnitus: Loud sounds can also cause tinnitus, which is a ringing or buzzing sound in the ears.
- Sleep disturbance: Loud sounds can interfere with sleep, making it difficult to fall asleep or stay asleep.
Sone 080 is a reference level for loudness that is defined as the loudness of a 1 kHz pure tone that is judged to be equally loud as a broadband noise with an equal power spectral density. It is a useful reference level for loudness because it is close to the average loudness of speech. This makes it a good starting point for adjusting the loudness of a sound system or for comparing the loudness of different sounds.
3. Psychoacoustics
Psychoacoustics is the study of how humans perceive sound. It is a branch of psychophysics, which is the study of how physical stimuli are perceived by humans. Psychoacoustics has a number of applications, including:
- The design of audio equipment
- The development of hearing aids and other assistive listening devices
- The study of noise pollution
- The development of new methods for music and sound synthesis
Sone 080 is a reference level for loudness that is used in psychoacoustics. It is defined as the loudness of a 1 kHz pure tone that is judged to be equally loud as a broadband noise with an equal power spectral density. Sone 080 is important in psychoacoustics because it provides a common reference point for comparing the loudness of different sounds. This is important for research on hearing and for the development of audio equipment and assistive listening devices.
The connection between psychoacoustics and sone 080 is essential for understanding how humans perceive sound. Psychoacoustics provides the theoretical foundation for the development of sone 080, and sone 080 provides a practical reference point for psychoacoustic research. Together, psychoacoustics and sone 080 provide a valuable tool for understanding and manipulating sound.
4. Audio engineering
Audio engineering is the art and science of recording, mixing, and reproducing sound. It encompasses a wide range of disciplines, including acoustics, electronics, and signal processing. Audio engineers work in a variety of settings, including recording studios, concert halls, and broadcast facilities.
Sone 080 is a reference level for loudness that is used in audio engineering. It is defined as the loudness of a 1 kHz pure tone that is judged to be equally loud as a broadband noise with an equal power spectral density. Sone 080 is important in audio engineering because it provides a common reference point for comparing the loudness of different sounds. This is important for tasks such as mixing and mastering audio recordings, and for designing sound systems.
For example, when mixing an audio recording, the audio engineer will use sone 080 as a reference level to ensure that the overall loudness of the recording is balanced. The engineer will also use sone 080 to compare the loudness of individual tracks, such as the vocals, drums, and bass. This helps to ensure that all of the tracks are at a similar level, and that the overall mix is cohesive.
Sone 080 is also used in the design of sound systems. For example, when designing a sound system for a concert hall, the audio engineer will use sone 080 to determine the appropriate level of amplification for the system. This ensures that the sound system is loud enough to be heard clearly by the audience, but not so loud that it causes discomfort.
Overall, sone 080 is a valuable tool for audio engineers. It provides a common reference point for comparing the loudness of different sounds, and it is used in a variety of applications, including mixing and mastering audio recordings, and designing sound systems.
5. Subjective
Sone 080 is a subjective measure of loudness, meaning that it is based on the perception of listeners rather than on any objective physical measurement. This is in contrast to sound pressure level (SPL), which is an objective measure of loudness that is based on the physical properties of the sound wave.
- Variability between individuals: The perception of loudness can vary significantly from person to person, depending on factors such as age, hearing sensitivity, and cultural background. This means that sone 080 may not be the same for everyone.
- Contextual dependence: The perception of loudness can also be influenced by the context in which the sound is heard. For example, a sound may seem louder in a quiet environment than in a noisy environment.
- Psychological factors: Psychological factors, such as expectations and emotions, can also affect the perception of loudness. For example, a person who is expecting a loud sound may perceive it as being louder than it actually is.
The subjective nature of sone 080 is important to consider when using it as a reference level for loudness. It is important to be aware that sone 080 may not be the same for everyone, and that the perception of loudness can be influenced by a variety of factors.
