WebThe lower threshold of human hearing is 0 dB at 1kHz. Moderate levels of sound (a normal speaking voice, for example) are under 60 dB. Relatively loud sounds, like that of a vacuum cleaner, measure around 70 dB. When workplace sound levels reach or exceed 85 dB, employers must provide hearing protection. A rock concert, at around 125 dB, is ... There are two sorts of light receptors in a bird's eye, rods and cones. Rods, which contain the visual pigment rhodopsin are better for night vision because they are sensitive to small quantities of light. Cones detect specific colours (or wavelengths) of light, so they are more important to colour-orientated animals such as birds.
