This application provides a voice gain control method, apparatus, voice control device, and storage medium, relating to the field of voice signal processing technology. The method includes: determining a target gain level for the current statistical period based on a first volume parameter of multiple frames of voice signals within a historical statistical period; and adjusting the second volume parameter of each frame of voice signal within the current statistical period based on a second volume parameter and the target gain level. This application can improve the stability of voice signal volume gain control.

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.

The invention discloses an audio signal adjusting method and device, virtual reality equipment and a storage medium. The method comprises the following steps: determining a binaural hearing threshold value of a current user; determining a first target audio signal and a second target audio signal according to the binaural hearing threshold; and adjusting a left sound production unit of the virtual reality equipment according to the first target audio signal, and adjusting a right sound production unit of the virtual reality equipment according to the second target audio signal. According to the invention, the volume of the left and right sound channels of the virtual reality equipment can be intelligently and independently adjusted according to the hearing difference between the two ears of the user, so that the effective sound pressure levels received by the two ears are balanced, and the immersion and comfort of VR experience are remarkably improved.

The invention discloses a decompression type hearing protection mechanism and an earphone in the technical field of hearing protection structures. The pressure reduction type hearing protection mechanism is applied to an earphone and specifically comprises a sound outlet channel, the sound outlet channel is detachably connected with the earphone, the sound outlet channel is sleeved with a blocking noise reduction part, and the blocking noise reduction part abuts against the outer wall of the sound outlet channel; an extrusion silencing part is sleeved outside the blocking silencing part, a contact part is arranged outside the extrusion silencing part, and the contact part is used for being in contact with an ear canal; and the material density of the blocking noise reduction part is higher than that of the extrusion noise reduction part. Wherein the earphone comprises a reduced-pressure hearing protection mechanism. Noise filtration and pressure reduction of the inner wall of the auditory meatus are effectively considered through different material densities of the blocking silencing part and the extrusion silencing part, so that the purpose of protecting hearing can be achieved on the basis of reducing the pressure of the auditory meatus.
