oder festen Stoff, die Ger\u00e4usche verursacht. Die Schallfrequenz (Tonh\u00f6he) bezeichnet die Anzahl an Schwingungen der Schallwelle pro Sekunde, gemessen in Hertz [Hz]. Der <b>H\u00f6rbereich des Menschen liegt zwischen 16 Hz und 20.000 Hz<\/b>, wobei der obere Frequenzbereich mit fortschreitendem Alter zu kleineren Frequenzen hin abnimmt. Das bedeutet, hohe T\u00f6ne werden von Erwachsenen zumeist schlechter wahrgenommen als von Kindern. Die f\u00fcr den Menschen nicht h\u00f6rbaren Schallwellen mit Frequenzen unterhalb von 16 Hz werden als Infraschall, solche mit einer Schwingungszahl von \u00fcber 20.000 Hz als Ultraschall bezeichnet. Diese werden von verschiedenen Tierarten zur Verst\u00e4ndigung oder zur Orientierung genutzt.<\/p><p class=\"align-justify\">Das menschliche Ohr als Sinnesorgan zur Aufnahme von Ger\u00e4uschen empfindet diese nicht nur leise oder laut, sondern auch angenehm oder unangenehm. Neben den physikalischen Gesetzm\u00e4\u00dfigkeiten sind daher auch die physiologischen Zusammenh\u00e4nge durch das subjektive H\u00f6rempfinden bei der Ger\u00e4uschbewertung von Bedeutung.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element

Eine Schallquelle hat eine konstante Schallleistung, die sich nicht \u00e4ndert, wenn sie in eine andere Raumumgebung abstrahlt (emittiert).<\/p><p class=\"align-justify\">Der Versuchsaufbau zur Messung der Schalleistung wird wie folgt vorgenommen: Die Ger\u00e4uschquelle ist aus, der L\u00fcfter ist an. Im Senderaum ist es still, aber durch den Ventilator entsteht ein Ger\u00e4usch im Empfangsraum. Durch die Mikrofone wird gemessen, wie viel von dem Ger\u00e4usch der L\u00fcftung im Empfangsraum ankommt.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0be3c95 animated-fast elementor-widget elementor-widget-image\" data-id=\"0be3c95\" data-element_type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;,&quot;_animation_delay&quot;:400}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"336\" src=\"https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Messverfahren-_zur-Schallemission_77047337f4.jpg\" class=\"attachment-large size-large wp-image-8266\" alt=\"Messverfahren der Schallleistung\" srcset=\"https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Messverfahren-_zur-Schallemission_77047337f4.jpg 500w, https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Messverfahren-_zur-Schallemission_77047337f4-300x202.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Angewandte Norm:\tDIN EN 23741<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\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-f2f3eb7 animated-fast elementor-widget elementor-widget-text-editor\" data-id=\"f2f3eb7\" data-element_type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;,&quot;_animation_delay&quot;:600}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><b>Berechnungsgleichung:<\/b><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-03f381e animated-fast elementor-widget elementor-widget-image\" data-id=\"03f381e\" data-element_type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;,&quot;_animation_delay&quot;:800}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"37\" src=\"https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Formel-Berechnung-der-Schallleistung_ad5d9b2431.png\" class=\"attachment-large size-large wp-image-8281\" alt=\"Formel zur Berechnung der Schallleistung\" srcset=\"https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Formel-Berechnung-der-Schallleistung_ad5d9b2431.png 500w, https:\/\/www.inventer.de\/wp-content\/uploads\/2021\/03\/csm_Formel-Berechnung-der-Schallleistung_ad5d9b2431-300x22.png 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\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-f016a6c animated-fast elementor-widget elementor-widget-text-editor\" data-id=\"f016a6c\" data-element_type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;,&quot;_animation_delay&quot;:800}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div><ul class=\"inventer-wave\"><li>L<sub>w\u00a0<\/sub>&#8211; Schalleistung der untersuchten Schallquelle [dB]<\/li><li>L<sub>p\u00a0<\/sub>&#8211; mittl.
