110 decibels is equivalent to the sound of a propeller plane taking off, karaoke, and a rock concert.

Decibel is the more commonly used unit of measurement. It can be expressed as:

1. A unit representing the ratio of power quantity, which is equal to 10 times the common logarithm of the ratio of power intensity.

2. A unit that represents the ratio of field quantities, equal to 20 times the common logarithm of the ratio of field strength and amplitude.

3. The unit of sound pressure level is approximately equal to the minimum division value at which the human ear can usually detect loudness differences.

Decibel originally came from the measurement of long-distance telecommunications, and has since been widely used in fields such as electrical engineering, radio, mechanics, shock vibration, mechanical power and acoustics.

Decibel is a non-SI unit selected by the country. It is a step difference unit in my country's legal measurement units. It is expressed as DB. It is defined as: "Two similar power quantities or quantities that can be compared with power." The common logarithm of the ratio times 10 equals 1."

At the same time, the "quantity comparable to power" is explained in the supplementary explanation of the People's Republic of China and the national statutory unit: "Usually refers to the square of the current, the square of the voltage, the square of the particle velocity, Sound pressure squared, displacement squared, velocity squared, acceleration squared, force squared, amplitude squared, field strength and sound energy density, etc.”

Extended information

1. Research shows that when the noise is 90 decibels, the sensitivity of rod cells in people’s retina to distinguish light brightness begins to decrease, and the reaction time to identify weak light is prolonged; When it reaches 95 decibels, the pupil will dilate; when it reaches 115 decibels, the eye's adaptability to light brightness will be reduced by 207. In addition, people who are exposed to noise for a long time are most likely to suffer from eye fatigue, eye pain, blurred vision and tearing.

2. Most of the general environmental noise comes from random noise sources, such as vehicles passing by, the honking of airplanes, the noise of people, and various noise sources around you.

3. During the combustion process, explosions, exhaust, and updrafts during combustion may affect the surrounding air disturbance. These phenomena will be accompanied by the generation of noise. Combustion equipment such as engines, boilers, smelting furnaces, turbines, etc. all produce this type of noise.

4. In daily life, various indoor household appliances, such as air conditioners, stereos, range hoods, televisions, and air-conditioning equipment, all produce noise. In addition; such as schools, Public places such as shopping malls, parks, and stadiums can also be regarded as noise-generating places.
