Human audibility curve
WebDetection could be especially limited where tracks curve around hills, reducing visibility and audibility of approaching trains, but no literature has examined this potential in the context of terrestrial transportation collisions with wildlife. At 10 locations in a mountain park where the railway curved around elevated topography, we… WebAs shown in [32], the human audibility curve is characterized by a sound pressure level (SPL) in dB that increases reducing the frequency, from values of very few dB at 1000 Hz to values of more than 70 dB at 20 Hz. Within the infra sound, the audibility only requires higher SPL, for example 100 dB at 10 Hz.

Webhuman brain. Spectral Energy Distribution Human listeners are sensitive to frequencies between 0.05 and 18 kHz [6]. However, the truly sensitive portion of this range lies between 0.25 and 8 kHz [6], setting approximate limits to the bandwidth of the acoustic communication channel The precise shape of the human audibility curve is conditioned ... Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. Meer weergeven Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels.
