    pitch, frequency sound and waves which are also dealing with physical science and how they our related. Sound is (a) the physical transmission of a disorder (energy) in a standard and the physiological response generally to pressure waves in air. However, the sound spectrum has much lower frequencies and is much simpler, with only three frequency regions; the infrasonic region (f<20Hz), the audible region (20Hz20 KHz), (Shipman-Wilson-Higgins, 2013). Depending on the volume of sound can be determined

  • Understanding Noise-Induced Hearing Loss

    903 Words  | 2 Pages

    Throughout our day to day lives we are exposed to many sounds such as the sound of traffic, coversation, TV, nature and music. More often than not these sounds that we experience are at a low safe level, levels that will not affect or harm our hearing. Unfortunatley when we are exposed to sound levels that are too high or loud sounds over a long period of time there is a chance that the delicate inner workings of the ear can be permanatly damaged. This is known as noise induced hearing loss (NIHL)

    external, anatomical portions of the auditory pathway: the pinna and ear canal. The pinna serves to collect sound from the environment and generate direction-dependent cues through spectral transformations (Hofman, et al, 1998; Raykar, et al, 2005). Sounds that are funneled into the ear canal contain a range of frequencies that are amplified and attenuated. This interaction of complex sound waves, based on the unique shape of an individual’s pinna, results in a transfer function used for localization
