Noise Spectrum

Noise is an unavoidable element of our lives and we encounter it in various forms every day. It can be caused by transport, industrial installations, home appliances and other sources. However, not all noise is equal, and their characteristics can vary significantly. One way to describe noise is by its spectrum.

The noise spectrum is the distribution of sound energy of noise across frequencies. In other words, it shows how much of the sound energy of the noise is contained in each frequency band. The noise spectrum is measured in decibels and presented as a graph, where frequencies are plotted along the X-axis, and the noise level in decibels is plotted along the Y-axis.

Knowledge of the noise spectrum is important for standardization and hygienic assessment of noise. Some frequencies may have a greater impact on a person than others. For example, noise with a frequency of 50-60 Hz, which is produced by electrical networks and electrical equipment, can cause headaches and sleep disturbances. Also, low-frequency noise can cause vibration, which can negatively affect human health.

It is important to note that the spectrum of noise can vary depending on many factors, including the source of the noise, distance from it, time of day, and other factors. Therefore, when hygienic assessment of noise it is necessary to take into account all these factors.

In conclusion, noise spectrum is an important parameter in describing and evaluating noise. It helps to better understand how noise affects people and allows appropriate measures to be taken to reduce its impact on human health.

Noises are sound vibrations that occur during the operation of various devices and machines, as well as during natural phenomena. One of the important parameters that determine the impact of noise on a person is the frequency distribution of sound energy. This distribution is called the noise spectrum. The noise spectrum plays an important role in environmental regulation and hygiene, since
