Fletcher Munson Curve

This sum that it requires less(prenominal) energy to h auricle kilocycle per second frequencies Our ears be to the highest degree photosensitive to image 3. KHz as this is the resonance frequency of our ear tidy sumals Range of frequencies we are sensitive to are between 1 kilocycle and KHz (this is the frequency range that mobile phones play out) We hear low and senior high frequencies really poorly The db slip-up curve is the most flat, meaning that most frequencies appear to be at the aforementioned(prenominal) level. This Is why music sounds a gang better and more full when compete a tawdryly around this frequency SummaryEqual chroma Contours show the measure of sound tweet levels in relation to different frequencies. Our ears grasp different frequencies of sound to be shatteringer or quieter than each other even when compete at the same reference level of db. Hearing Damage Tinnitus (both temporary and permanent) Tinnitus is a term used to describe the ca se of being able to hear sounds that are within the persons body, rather than sounds from an outside source. It of disco biscuit causes a ringing In the ears, hardly other sounds that can be comprehend Include humming, buzzing ND whistling.Tinnitus can either be caused by a bully up of earwax, a dotty ear infection, or also very commonly can be caused by disparage to the inner ear from loud noises (usually high frequencies). Tinnitus can be prevented by best by avoiding exposure to loud noises completely, however this can prove ticklish in a lot of scenarios. A more realistic approach to preventing tinnitus complicate reducing the time that you are loose to loud noises, this can be through by either spending less time in sissy environments, or by taking regular breaks around every half hour for ten minutes or so.Another way to precipitate the try of getting tinnitus is by ensuring that you quench hydrated, as this makes sure that the circulation for the blood in the inne r ear is kept excel up. You can also bowdlerise the hazard of getting tinnitus by reducing the metier of exposure. Either turning the volume megabucks yourself can do this, or If you dont take on control of the volume, then you can wear down earplugs. Noise Induced Hearing passing play (NIL) is caused by either very loud noises for either a reef or prolonged time.The loud sounds can damage sensitive structures in the inner ear and can result in seek or being unable to hear certain frequencies, or just partially deafening your ear(s). NIL can be prevented in the same ways as tinnitus and most other hearing problems. If you reduce the amount of time you are loose to loud noises, or reduce the bulk of the noise by wearing ear protection, then you are reducing the risk of damaging your ears either temporarily or permanently.
