cause the machine structure to vibrate. These vibrations (structure-borne sound) are transmitted to the air via the machine surface and are converted into airborne sound. If this air vibration is sufficiently large, we perceive it as noise. In the case of a very high intensity, this can even be a noise that is harmful to human ears.<\/p><p>Furthermore, large vibrations can damage the machine structure in the long term.

If this sound increases in volume, unpleasant noise is created. The focus is therefore often on reducing or modifying them. In order to gain an understanding of the possibilities for change, it is first important to understand the starting point. For this reason, the origin of one of these noises is explained in more detail in the following section.<\/p><h5><span style=\"color: #112233;\">Origin<\/span><\/h5><p>First of all, a mechanical process is required to convert the energy. This often involves converting electrical energy into dynamic forces or torques. This is the case, for example, with an electric motor in a metal-cutting machine. Multiple conversions can also occur within a machine. The electric motor drives the tool, but the interaction between the tool and the workpiece also generates forces (cutting forces). For this reason, various location-dependent dynamic forces act inside the machine structure. It can therefore be stated that the dynamic behavior inside the machine is superimposed with working forces.<\/p><h5><span style=\"color: #112233;\">Consequences<\/span><\/h5><p>The internal dynamic forces also cause the surface of the machine to vibrate. As soon as this occurs, the vibration is also transferred to the air surrounding the machine. In concrete terms, this means that the air is pressed and compressed, which in turn can lead to a dynamic air pressure fluctuation that spreads throughout the room. If this air pressure fluctuation is sufficiently large and at an audible frequency, we perceive it as a sound. The intensity and tone of the sound are in turn directly dependent on the amplitude and frequency of the air pressure fluctuation. The following illustration shows the described generation mechanism graphically.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-7566 size-full\" src=\"https:\/\/holo-metrix.com\/mystaging01\/wp-content\/uploads\/2021\/10\/Machinenakustik_Grafik-2.png\" alt=\"\" width=\"993\" height=\"71\" srcset=\"https:\/\/holo-metrix.com\/wp-content\/uploads\/2021\/10\/Machinenakustik_Grafik-2.png 993w, https:\/\/holo-metrix.com\/wp-content\/uploads\/2021\/10\/Machinenakustik_Grafik-2-300x21.png 300w, https:\/\/holo-metrix.com\/wp-content\/uploads\/2021\/10\/Machinenakustik_Grafik-2-768x55.png 768w\" sizes=\"(max-width: 993px) 100vw, 993px\" \/><\/p><h5><span style=\"color: #112233;\">Solution<\/span><\/h5><div class=\"\" data-block=\"true\" data-editor=\"7q3k7\" data-offset-key=\"cm69h-0-0\"><div class=\"public-DraftStyleDefault-block public-DraftStyleDefault-ltr\" data-offset-key=\"cm69h-0-0\"><p>Along this acoustic chain of origin, machine acoustics takes the approach of eliminating the noise as early as possible. Ideally, in such a way that the disturbing noise does not arise in the first place.<\/p><p>Nevertheless, it may be the case that no sensible or economical solution can be found for a machine that eliminates the source of a noise. In such cases, passive elements are used to reduce or absorb the resulting noise. A typical example of this is the noise barrier in road traffic.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-25f7b4e5 elementor-widget elementor-widget-heading\" data-id=\"25f7b4e5\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">In which production stages are machine acoustic analyses used?<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-75065d23 elementor-widget elementor-widget-text-editor\" data-id=\"75065d23\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Machine acoustic analyses are used in various phases of the product life cycle of machines. HoloMetrix GmbH offers you its experience and services for noise reduction in every phase. The following list presents a few typical use cases in the most important phases where we are happy to support you:<\/p><h5><span style=\"color: #112233;\">Software Development<\/span><\/h5><p>At this stage, it may be of interest to record the actual acoustic condition. Acoustic measurements are used for this purpose. Typical questions that are asked in this context are Is the target being achieved? Are further acoustic measures necessary? Such measurements can be supplemented by benchmarking (comparative measurements). Furthermore, identification measurements also play a decisive role in detecting acoustic problem zones.<\/p><h5><span style=\"color: #112233;\">Production<\/span><\/h5><p>At the production stage, acoustic measurements are often used for quality assurance. This requires a precisely defined measurement procedure so that the results remain comparable and \u201ccontrollable\u201d at a later stage. By means of an update measurement, the acoustic results obtained can be incorporated into the development process, especially in the calculation departments. This serves to make future predictions even more accurate.<\/p><h5><span style=\"color: #112233;\">Application phase<\/span><\/h5><p>Particularly in the case of larger stationary systems, which may also represent a larger investment, the acoustic properties should not change significantly over the operating time. Supplementary measurements and their comparison with previous measurement results are therefore also useful at this point. Furthermore, acoustic measurements and their subsequent FFT analysis allow potential weak points to be identified and rectified at an early stage.<\/p><p>The field of machine acoustics is very comprehensive and versatile.
