Abstract: A Chinese herbal medicine composition for improving hearing impairment comprises at least two of avocado extract, ecklonia cava extract and perilla extract. The Chinese herbal medicine composition can effectively reduce a NO content secreted by cells, reduce an inflammatory reaction of cells, and have a good effect of improving LPS-induced hearing loss. Moreover, ingredients of the Chinese herbal medicine composition are medicine-and-food homologous ingredients, which have no obvious cytotoxicity and obvious side effects.

Abstract: The invention discloses a Chinese herbal medicine composition for relieving hearing loss and a preparation method and use thereof. The Chinese herbal medicine composition is prepared from at least two of the medicinal and edible raw materials of rhizoma curcumae longae, Dendrobium nobile and fructus Piperis longi, can effectively reduce the content of NO secreted by cells, reduces cell inflammation, and has a good effect of relieving hearing loss induced by LPS. The Chinese herbal medicine composition is not a simple combination of traditional Chinese medicines and has a synergistic effect. The Chinese herbal medicine composition can significantly reduce ABR value, MDA, and glutamic acid of a patient with hearing loss, significantly relieves hearing loss, and can be developed into functional foods and medicines for relieving hearing loss as an active ingredient.

Abstract: A cycling helmet capable of switching a sound production guidance mode based on a bone conduction earphone includes: a helmet body and the bone conduction earphone disposed on the helmet body. The bone conduction earphone includes a magnet, a coil and a bone conduction oscillator, and the bone conduction oscillator can contact the helmet body, so as to cause the helmet body to oscillate to form a sound cavity.
