A hearing protection apparatus has a pair of assemblies, each assembly including a body, an attachment facility connected to the body and configured to removably receive a lower edge of a hat, a retractable tether extending from the body and having a free end, and an earplug attached to the free end of the retractable tether. The attachment facility may be a clip defining an upwardly open channel. There may be a hat having opposed right and left edge locations each proximate to a wearer's ear, and the attachment facilities may be connected respectively to the right and left edge locations. A retraction actuator may be connected to the body and operable to retract the tethers to a retracted condition in response to actuation of the retraction actuator. There may be separate retraction actuators for each assembly, the retraction actuators being operable independently of each other.

The utility model relates to the technical field of protective appliance especially is concerned on a kind of noise reduction goggles, including mirror frame and temple, the both ends of mirror frame are hinged respectively with temple, mirror frame is equipped with goggles lens, temple is equipped with noise reduction pendant, noise reduction pendant is equipped with adjusting mechanism, cotton thread and noise reduction earplug, one end of cotton thread is connected in adjusting mechanism, its other end is connected in noise reduction earplug, adjusting mechanism is installed in temple, and the length of cotton thread is adjusted, to release or retract noise reduction earplug. From the above, the efficient integration of the goggles and the noise reduction earplug is achieved, providing one-key retracting and automatic indexing function, significantly improving user experience and operation convenience, while ensuring the stability and safety of the equipment, suitable for a variety of high-noise scenes, meeting the user's needs in protecting eyes and hearing, also improving the practicability and aesthetics of the product.

This utility model discloses an adaptive tilt pressure sealing ring and a noise-canceling earplug. The sealing ring includes a sealing lip, which comprises a lip tip and a lip body. The lip tip abuts against the front end of the lip body and forms an integral structure with it. The outer surface of the lip body extends backward and outward at an angle, so that the lip body gradually thickens backward. The inner wall of the sealing lip, corresponding to the main body of the lip body, forms a rearward and outward inclined surface, so that the inner cavity of the sealing lip corresponding to the main body of the lip body forms an flared structure that gradually widens from front to back. This allows the sealing lip to undergo gradual deformation under force, automatically adjusting the deformation direction under tilt pressure, increasing the contact area. The deformation direction can be adjusted through the deformation cooperation between the lip tip and the lip body, eliminating the risk of leakage and improving the noise-canceling effect of the earplug.

This invention discloses a high-density closed-cell polyurethane structure and its application in earplugs or earmuffs, belonging to the field of polymer materials technology. By weight, it comprises the following components: 30-40 parts of polyether polyol I, 10-20 parts of polyether polyol II, 5-15 parts of chain extender, 1-3 parts of organosilicon surfactant, 1-3 parts of hydrophobic silica, 8-15 parts of foaming agent, 19-42 parts of polymethylene polyphenyl polyisocyanate, 8-12 parts of pyridine-amide-terminated diisocyanate, and 6-10 parts of ureidopyrimidinone diisocyanate. Compared with existing technologies, the polyurethane earplugs of this invention have excellent overall performance; the self-healing network and rigid closed-cell foam wall structure work synergistically, exhibiting good repeatability and suitability for large-scale production.

A system and method for noninvasive sleep monitoring are disclosed. The system includes an in-ear biosensor system (“biosensor system”) and a data analysis system. The biosensor system includes at least one earbud placed at or within an ear canal of an individual. The earbud includes an acoustic sensor that detects biosignals including infrasonic and audible signals from the individual in the ear canal. A controller board of the biosensor system collects and forwards the biosignals to the data analysis system. The data analysis system analyzes the biosignals to identify and monitor physiological information of the individual during sleep. The physiological information includes sleep stages, sleeping position information, sleep events including snore, breathing cessation and bruxism events, and sleep disorders, in examples. The system can also induce changes to the physiological information during sleep using external stimuli to improve a quality of sleep.

An electroacoustic transducer of the present invention includes: a cylindrical external auditory canal insertion part that is part of a hollow housing to be worn in an ear of a user, and that is provided at an external auditory canal side of the housing; a measurement unit that measures electrostatic capacitance by using an electrode provided inside the external auditory canal insertion part; and an earpiece and a conductive layer, as a conductive part, arranged outside the external auditory canal insertion part and around the electrode.
