Abstract

A protective suit against sound waves with which it is possible to achieve a considerable reduction of the effects of sound waves on the human body. The suit material is furnished with at least two flexible soundproofing layers, of which at least one layer increases the weight per unit area of the suit, and another acts as a cushioning layer.

Description

Die Erfindung bezieht sich auf einen Schutzanzug gegen Schallwellen.The invention relates to a protective suit against sound waves.

Auf die Kcrperperipherie eines Menschen einwirkende Schallwellen werden insbesondere bei Lärmpegeln oberhalb der Lärmschmerzgrenze auch auf das Körperinnere übertragen. Der Kreislauf und die inneren Organe können dadurch schallmäßig so belastet werden, daß Durchblutungsstörungen, Übelkeit und andere vegetative Reaktionen ausgelöst werden. Zum Schutze gegen die Schallübertragung über die Körperperipherie gibt es bereits Schallschutzanzüge (Overalls), die aus verdicktem Material, wie z. B. Leder oder Textilgewebe, bestehen. Die Materialdicke der Schutzanzüge beträgt hierbei ca. 1 bis 2 mm. Es werden auch Schallschutzwesten, die nur den Rumpf abdecken, oder als Nierenschutz wirkende Leibbinden angeboten. Manche Schutzanzüge haben im Nierenbereich doppelte Materialdicken.Sound waves acting on the periphery of a person's body are also transmitted to the inside of the body, particularly at noise levels above the noise pain limit. The circulation and the internal organs can be so burdened by sound that triggers circulatory disorders, nausea and other vegetative reactions. To protect against sound transmission over the periphery of the body, there are already soundproof suits (overalls) made of thickened material, such as. B. leather or textile. The material thickness of the protective suits is approx. 1 to 2 mm. There are also soundproof vests that only cover the torso, or body bandages that act as kidney protection. Some protective suits have double material thicknesses in the kidney area.

Bekanntlich hängt die Schalldämmung stark von dem Flächengewicht des Schutzmaterials ab. Das Flächengewicht der bekannten Schutzmaterialien liegt bei ca. 1,5 kg/m . Als Luftpolster wirkt dazu noch die darunter befindliche Arbeitskleidung, deren Dicke in der Regel 3 bis 5 mm nicht übersteigt.As is well known, sound insulation strongly depends on the basis weight of the protective material. The basis weight of the known protective materials is approximately 1.5 kg / m. The work clothing underneath, whose thickness generally does not exceed 3 to 5 mm, also acts as an air cushion.

Hohe Lärmpegel bis zu 130 dB (A) treten z. B. in Produktionshallen mit schnell laufenden Schlagpressen oder bei Reparaturen und Testläufen von Strahltriehwerken auf. Die spektrale Verteilung des auftretenden breitbandigen Lärms reicht über den gesamten Hörbereich. Die Dämmwirkung der bekannten Schutzanzüge bzw. Schutzteile setzt erst oberhalb von 1000 Hz ein, so daß alle darunterliegenden Schallfrequenzen auf die Körperperipherie übertragen werden. Sie bieten deshalb keinen genügenden Schutz gegen Schallwellen.High noise levels up to 130 dB (A) occur e.g. B. in production halls with high-speed impact presses or for repairs and test runs of jet trenchers. The spectral distribution of the broadband noise occurring extends over the entire listening area. The insulation effect of the Known protective suits or protective parts are only used above 1000 Hz, so that all underlying sound frequencies are transmitted to the periphery of the body. Therefore, they do not offer sufficient protection against sound waves.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schutzanzug zu schaffen, bei dem die Schallübertragung auf die Körperperipherie und in das Körperinnere bei noch akzeptablem Gesamtgewicht und Dickenmaß des Anzuges auf ein Mindestmaß verringert wird.The invention is therefore based on the object of providing a protective suit in which the transmission of sound to the periphery of the body and into the inside of the body is reduced to a minimum while the overall weight and thickness of the suit are still acceptable.

Diese Aufgabe ist nach der Erfindung dadurch gelöst, daß mindestens zwei flexible Schallschutzschichten vorgesehen sind, deren eine eine Beschwerungsschicht und deren andere eine Polsterschicht aufweist. Durch diese Schutzschichten wird erreicht, daß die Schutzwirkung des erfindungsgemäßen Anzugs schon bei wesentlich tieferen Frequenzen als 1000 Hz einsetzt, wodurch der in den Körper eingeschallte Schalldruckpege: gerade in dem aus medizinischer Sicht bedeutsamen mittleren und hohen Frequenzbereich wesentlich vermindert wird.This object is achieved according to the invention in that at least two flexible soundproofing layers are provided, one of which has a weighting layer and the other of which has a cushioning layer. Through these protective layers it is achieved that the protective effect of the suit according to the invention already starts at substantially lower frequencies than 1000 Hz, as a result of which the sound pressure level penetrated into the body is significantly reduced, especially in the medium and high frequency range which is important from a medical point of view.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels und der Zeichnung. Es zeigen:

  • Fig. 1 einen Querschnitt eines Ausführungsbeispiels des mit Schutzschichten versehenen Schutzanzuges nach der Erfindung und
  • Fig. 2 eine graphische Darstellung des Dämmverlaufs eines Schutzanzuges nach der Erfindung im Vergleich zu einer herkömmlichen Ausführung.
  • Fig. 1 zeigt den Querschnitt des Aufbaus eines Schutzanzuges mit flexiblen Schutzschichten. An der Innenseite 1 des Grundmaterials 2 , das beispielsweise aus Leder oder elnem schweren Textilgewebe bestehen kann, ist eine Beschwerungsschicht 3 und eine daran anschließende Polsterschicht 4 angeordnet. Die zu dämmenden Schallwellen treffen auf der Aussenseite 5 des Grundmaterials 2 auf.
Further features and advantages of the invention emerge from the subclaims and from the following description of an exemplary embodiment and the drawing. Show it:
  • Fig. 1 shows a cross section of an embodiment of the protective suit provided with protective layers according to the invention and
  • Fig. 2 is a graphical representation of the insulation course of a protective suit according to the invention compared to a conventional embodiment.
  • Fig. 1 shows the cross section of the structure of a protective suit with flexible protective layers. On the inside 1 of the base material 2, which can consist, for example, of leather or a heavy textile fabric, a weighting layer 3 and an adjoining cushion layer 4 are arranged. The sound waves to be insulated hit the outside 5 of the base material 2.

Die Beschwerungsschicht 3 besteht bei dem Ausführungsbeispiel aus plattenförmigen, zueinander in Abstand gehaltenen, vorzugsweise rasterförmig angeordneten Beschwerungselementen 6 und ist z. B. aus elastischem Kunststoffmaterial hergestellt. Sie kann aber auch streifenförmig oder als durchgehende flexible Folie ausgebildet sein. Das Flächengewicht der Beschwerungsschicht 3 sollte zwischen 4 und 6 kg/m2 liegen, damit des Gesamtgewicht des Anzuges nicht zu groß wird. Die Beschwerungsschicht 3 kann ihren verschiedenen Ausführungsformen nach am Grundmaterial 2 angeklebt oder mittels eines dünnen, leichten Gewebes 7 angesteppt sein.In the exemplary embodiment, the weighting layer 3 consists of plate-shaped weighting elements 6, preferably spaced apart from one another, preferably arranged in a grid, and is e.g. B. made of elastic plastic material. However, it can also be in the form of a strip or as a continuous flexible film. The weight per unit area of the weighting layer 3 should be between 4 and 6 kg / m 2 , so that the total weight of the suit does not become too large. According to its various embodiments, the weighting layer 3 can be glued to the base material 2 or quilted by means of a thin, light fabric 7.

Die sich über der Beschwerungsschicht 3 befindliche Polsterschicht 4 ist in dem Ausführungsbeispiel kissenförmig als eingesteppte Luftkissen oder Wattekissen dargestellt, die entweder durch ein leichtes Innenfutter 8 gehalten wird oder mit dem Gewebe 7 bzw. der Beschwerungsschicht 3 haftend verbunden ist. Sie kann aber auch streifen- oder flächenförmig ausgebildet sein und beispielsweise aus Schaumstoff bestehen. Die Dicke der Polsterschicht sollte mindestens 15 mm betragen, wegen einer ausreichenden Beweglichkeit mit einem derartigen Schutzanzug sollte aber eine Dicke von 30 mm nicht überschritten werden. Das Gewicht der Polsterschicht 4 kann im Hinblick auf die Beschwerungsschicht 3 vernachlässigt werden.The cushion layer 4 located above the weighting layer 3 is shown in the exemplary embodiment in the form of a cushion as a quilted air cushion or cotton cushion, which is either held by a light inner lining 8 or is adhesively connected to the fabric 7 or the weighting layer 3. However, it can also be in the form of strips or sheets and, for example, be made of foam. The thickness of the cushion layer should be at least 15 mm, but due to sufficient mobility with such a protective suit, a thickness of 30 mm should not be exceeded. The weight of the cushion layer 4 can be neglected with regard to the weighting layer 3.

Bei den Untersuchungen zur Verbesserung der Dämmwirkung bei Schutzanzügen wurde festgetellt, daß sie sowohl vcm Flächengewicht des Anzugmaterials als auch von der Dicke des sich anschließenden sogenannten Luftpolsters abhängt. Eine Vergrößerung des Flächengewichtes, der natürlich wegen des Gesamtgewichtes des Schutzanzuges Grenzen gesetzt sind, oder eine Vergrößerung der Dicke einer Polsterschicht führt im Hinblick auf die im Lärmspektrum enthaltenen Frequenzen zu einer früher einsetzenden Schutzwirkung.In the investigations to improve the insulation effect in protective suits, it was found that it depends both on the basis weight of the suit material and on the thickness of the so-called air cushion. An increase in the weight per unit area, which of course is limited due to the total weight of the protective suit, or an increase in the thickness of a cushion layer leads to an earlier protective effect with regard to the frequencies contained in the noise spectrum.

In Fig. 2 ist die Dämmwirkung des erfindungsgemäßen Schallschutzanzuges im Vergleich zu einem handelsüblichen Schutzanzug dargestellt. Die Kurve A bezieht sich auf einen Lederoverall ohne zusätzliche Schutzschichten. Eine Dämmwirkung setzt hier erst ab einer Frequenz von 1000 Hz ein. Die Kurve B zeigt das Dämmverhalten eines erfindungsgemäßen Schutzanzuges mit zwei Schallschutzschichten und zwar mit einer Beschwerungsschicht 3 mit einem Flächengewicht von 5 kg/m2 und einer 30 mm dicken Polsterschicht 4. Die Dämmwirkung beginnt hierbei schon nach 160 Hz und verbessert sich bei höheren Frequenzen um bis zu 25 dB.2 shows the insulation effect of the soundproofing suit according to the invention in comparison to a commercially available protective suit. Curve A relates to a leather overall without additional protective layers. An insulation effect only starts here at a frequency of 1000 Hz. Curve B shows the insulation behavior of a protective suit according to the invention with two soundproofing layers, specifically with a weighting layer 3 with a basis weight of 5 kg / m 2 and a 30 mm thick cushion layer 4. The insulation effect starts here after 160 Hz and improves at higher frequencies up to 25 dB.

Mit dem erfindungsgemäßen Schutzanzug wird somit eine wesentlich bessere Dämmwirkung von Schallwellen auf die menschliche Körperperipherie erzielt und eine höhere Schutzwirkung in arbeitsmedizinischer Hinsicht erreicht. Bei der Herstellung von Schutzanzügen nach der Erfindung, die bei den angegebenen Größen der Schutzschichten noch ein akzeptables Gesamtgewicht ergeben und eine ausreichende Beweglichkeit gewähren, sollte darauf geachtet werden, daß die Öffnungen für die Beine und besonders für die Arme durch einen Bund gut verschlossen werden.With the protective suit according to the invention, a significantly better insulation effect of sound waves on the human body periphery is achieved and a higher protective effect is achieved in occupational medicine terms. In the production of protective suits according to the invention, which still give an acceptable overall weight with the given sizes of the protective layers and allow sufficient mobility, care should be taken that the openings for the legs and especially for the arms are well closed by a collar.
