Average long term speech spectrum (talking over one minute). General. Though were capable of distinguishing between 1400-odd pitches, most of the important speech-related sounds fall within a narrow, relatively low spectrum. Age related hearing loss (or presbycusis) naturally develops as we age and our hearing can begin to deteriorate as a result of external factors, including the environment and existing medical conditions. Though a normal audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. is our place to explore ideas and themes of interest. The implication is that, depending on the average volume, all frequency ranges outside of the 3 kHz to 4 kHz range must be as much as 10 decibels louder to be perceived as being at the same volume. (Perception is commonly defined to be awareness through the senses, a typically circular definition of higher-level processes in living organisms.) This is true for the middle frequency range (1-2 kHz). Lower frequency sounds like the roar of a wind turbine are also out of the human hearing range and are often felt as vibrations rather than heard as sound. It is at the lowest pedal. It is capable of detecting pressure variations of less than one billionth of atmospheric pressure.The threshold of hearing corresponds to air vibrations on the order of a tenth of an atomic diameter. Hearing loss usually affects the higher pitches first of the human hearing range. Loudness corresponds to the intensity of a sound while pitch corresponds to the highs or lows of a frequency.
