35 results about "Noise-induced hearing loss" patented technology

Devices and methods for digital sound leveling are disclosed. The subject devices and methods can be used to reduce the risk of noise induced hearing loss. According to an embodiment, an audio file can be parsed into frames that are filtered using an A-weighted digital filter and scaled to a desired power level. Accordingly, the dynamic range of an audio output at a particular volume level can be controlled.

Peptides for the treatment of inflammation, and therapeutic uses and methods of using the same are disclosed. Peptides including a transducing sequence are effective for inhibiting cytokine activity and TNF-α secretion through interaction with toll-like receptor signaling pathways. Experiments are described illustrating the efficacy of the compounds in treating otitis media, noise-induced hearing loss, age-related hearing loss, and improvement of ordinary hearing.

Loud sounds with fast rise times, like gunfire and explosions, can cause noise-induced hearing loss (NIHL). Unfortunately, current models do not adequately explain how impulsive sounds cause NIHL, which makes it difficult to predict and prevent NIHL on battlefields and other hostile or rugged environments. Fortunately, the impulsive sounds experienced by soldiers and others working in rugged environments can be recorded using a compact, portable system that acquires, digitizes, and stores high-bandwidth audio data. An example of this system can be mounted on a helmet or other article and used to record hours of audio data at a bandwidth of 20 kHz or higher, which is broad enough to capture sounds with rise times less than 50 ms. An analog-to-digital converter (ADC) digitizes these broadband audio signals at rate of 40 kHz or higher to preserve the impulse information. A processor transfers the digitized samples from a buffer to a memory card for later retrieval using an interrupt-driven processing technique.

The invention discloses a nutritional agent with noise reduced hearing loss resistance. The nutritional agent is prepared from the following raw materials in parts by weight: 600-1000 parts of N-acetyl-L-cysteine, 1-4 parts of vitamin A, 1-5 parts of vitamin B1, 1-5 parts of vitamin B2, 1-10 parts of vitamin B6, 0.01-0.05 part of vitamin B12, 60-1000 parts of vitamin C, 15-300 parts of vitamin E which is based on alpha-totaxin, 50-400 parts of magnesium and 79-3175 parts of food acceptable accessories. Experiment data displays that the nutritional agent has remarkable effect of preventing and controlling the noise induced hearing loss. The nutritional agent can be used for enhancing the anti-oxidation ability of the organism and lightening the exitotoxicity damage, has the characteristics of being remarkable in curative effect, low in potential toxicity and low in cost, and is suitable for the noise reduced hearing loss protection and daily nutrient supplementation of people who live and work in the environment with continuous exposed high-intensity noise.

The invention provides a method of treating noise-induced hearing loss, the method including the step of administering an A1 adenosine receptor agonist to a patient in need thereof. In a particularly preferred embodiment the A1 adenosine receptor agonist is a selective A1 adenosine receptor agonist.

The present invention provides methods of preventing, treating, and / or reducing noise induced hearing loss and / or noise-induced inner ear trauma. The methods include the administration of glatiramer acetate or a derivative thereof and, optionally, at least one anti-oxidant.

The present invention relates to a pharmaceutical composition for preventing or treating hearing impairment containing cilostazol and ginkgo biloba extract as active ingredients, the pharmaceutical composition inhibits the apoptosis of auditory cells caused by the generation of reactive oxygen species (ROS), Thereby, noise-induced hearing impairment or ototoxic hearing impairment can be effectively prevented or treated.

The invention relates to a noise stimulation box, which has a main function of providing a noise giving environment for experimental animals during noise stimulation. The noise stimulation box is implemented by a lightweight sound insulation component and a double-layer composite sound insulation structure in order to improve the sound insulation performance and meet the special requirements of the noise simulation box on ventilation, fireproofness, moisture proofness, corrosion resistance and the like. The noise stimulation box disclosed by the invention furthest ensures the strength stability and the minimum attenuation after a noise signal of a signal generator is output, furthest meets the requirements on normalization of noise stimulation models and provides an effective environment foundation for establishment of the noise-induced deaf animal models. The noise stimulation box relates to the field of scientific research of the experimental animals, sound wave barrier sound-absorbing materials, physical ventilation and the like and is suitable for establishment of various noise-induced hearing loss animal models and sound stimulation models as well as behavior surveillance of the experimental animals under the noise exposure.
