装着使用を防止することにある。People working in places with a lot of noise, such as airports, use soundproof ear covers to avoid noise or to prevent hearing organ damage (such as hearing loss) resulting from noise. Conventionally known soundproof ear coverings are quite effective as soundproofing tools if they are worn and used so that noise does not directly enter the ears. If there is a gap between the head and
There is a disadvantage that noise directly enters the soundproof ear cover through the gap, and the soundproofing effect is significantly reduced, and the desired effect cannot be obtained. SUMMARY OF THE INVENTION It is an object of the present invention to provide a soundproofing ear cover and a wearer (and surroundings) using an alarm sound or a warning light when there is a gap between the soundproofing ear cover and the head when the soundproofing ear cover is not properly mounted. The purpose of this is to prevent the user from wearing the device in a state where the desired soundproofing effect has not been obtained.

In the drawing, reference numeral 1 denotes a cup-shaped jacket for a soundproof ear cover. A sound-insulating material layer 2 made of a synthetic resin sponge or the like is provided inside the cup-shaped jacket 1 in the same manner as a conventionally known sound-insulating ear cover. A cushion member 3 that is in contact with and in close contact with the portion is attached. A microphone 4 for sensing the sound pressure inside the soundproof ear cover is attached inside the soundproof material layer 2, and an alarm buzzer 5 and a warning light 6 are provided between the cup-shaped jacket 1 and the soundproof material layer 2. , Microphone 4
An electric circuit 7 for activating an alarm buzzer 5 and an alarm light 6 when the level of the electric signal from the electric signal is compared with a comparison reference value and the level exceeds the comparison reference value, and a power supply battery 8 are provided. In the drawing, reference numeral 9 denotes an alarm sound passage of the alarm buzzer 5, and reference numeral 10 denotes a wearing headband that connects and holds left and right soundproof ear covers. The cup-shaped jacket is made of a synthetic resin material, cloth, or the like.

装着不良を知らせる。[0005] In the above-described soundproof ear covering, when the device is used, there is a gap between the cushion member 3 and the outer surface of the head, so that the sound pressure (noise level) in the sound insulating ear cover exceeds a specified value. When the electric signal level rises and exceeds the comparison reference value, the buzzer 5 and the alarm 6
Is activated to notify the wearing user of the soundproof ear covering and the surrounding persons of the improper wearing.
