Abstract: A construction helmet is disclosed having a housing detachably mounted thereon which supports a ratcheted take-up reel having a pair of ear plugs attached to a hub by flexible cords wound about the hub. The reel is rotatably carried on the housing and a manually operable plunger releases the reel for automatic withdrawal of the ear plugs into a storage receptacle on the housing. Strain relief elements are attached to each cord and the receptacle includes shoulder straps engageable with the strain relief elements. The plunger is releasably connected to ratchet teeth carried on the reel hub.

Abstract: An earplug selectively insertable into an ear canal for protection of the ear is attached to an elastic band that can be looped around the ear to retain the earplug immediately adjacent the ear even when the plug is removed from the ear canal. The elastic band may be an endless band or a strap having end portions adjustably connected together as desired to form a band of the desired size.
Abstract translation: 可选择性地插入到耳道中用于保护耳朵的耳塞被附接到可围绕耳朵环绕的弹性带，以便即使当耳塞从耳道移除时也将耳塞紧紧地保持在耳朵附近。 弹性带可以是环形带或具有根据需要可调节地连接在一起以形成所需尺寸的带的端部的带。

Abstract: The present invention falls within the field of articles for daily use, and particularly relates to a sleep noise-proof structure provided on an eye-shrouding member being an eye patch or a sleeping cap and having an eye shield for shrouding the eyes, wherein the sleep noise-proof structure comprises two wires and two earplugs, the wires have a first end and a second end, and the first end is fixedly connected to the front side of the eye shield, and the second end is connected to an earplug. Since the earplug is connected to the front side of the eye shield with a wire, not only the problem of loss of the earplug can be prevented, but also the ear cannot be tightened and the overall comfort can be increased for a better experience.

Abstract: A hearing protection device is presented. The hearing protection device includes a first and second earmuffs (202, 260, 310) connected by a connector (270, 320). The first and second earmuffs are configured to provide level dependent hearing protection. The first earmuff includes a microphone element (204, 330) having a microphone entry (264), positioned on an exterior of a housing of the first earmuff (260), the microphone element (204, 330) being configured to receive an ambient sound. The first earmuff also includes a processor configured to process the ambient sound using a level dependent function. The first earmuff also includes a speaker configured to broadcast the processed ambient sound in an interior of the first earmuff. The first earmuff also includes an asymmetrical windscreen (262) configured to enclose the microphone element. The windscreen is coupled to the housing of the first earmuff.

Abstract: A hearing protection device (500) arranged to provide an acoustic barrier is disclosed. The hearing protection device (500) includes a microphone (502) arranged to measure sound behind the acoustic barrier. The device (500) determines whether a sound level characteristic of the sound measured by the microphone (502) is above a predetermined threshold. When the sound level characteristic measured by the microphone (502) is above the predetermined threshold, the device (500) compares the sound level characteristic of the sound behind and outside the acoustic barrier to determine an attenuation of the device (500). If the determined attenuation is below a cut-off level of attenuation, the device (500) provides an alert.
