which of the following has the possibility of minimum frequency of voice?
Answers
Answer:
where the heck are the options
Answer:
For human ears, the audible range is 20 Hz to 20,000 Hz. The lower the frequency of vibration, the higher is the pitch. Unwanted or unpleasant sound is termed as music.
Explanation:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. ... The vibration of a source sets the amplitude of a wave. It transmits energy into the medium through its vibration
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. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal.
Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14–16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).
