How many different types of sound are there?
All sound is the same, just at different frequencies and volume. However sound is often categorised into three groups. Subsonic - Low frequency, below the threshold of human hearing. 25 hertz or less. Audible - Any sound a normal human being can hear. 25 Hertz - 18 Kilo Hertz. Ultrasonic - High frequency sound, above the threshold of human hearing. 18 Kilo hertz and above. It should be noted that some animals such as dogs and bats can hear much higher frequencies than humans. Also note, the upper limit of human hearing varies from person to person, and decreases with age. 18 - 18.5 kilo hertz is normally the upper limit for most people.

How many hertz can a pigeon hear?
Pigeons can hear frequencies as low as .1 Hz, or one vibration every ten seconds! This allows pigeons to hear the infrasonic sounds of ocean waves breaking on the coastline. By positioning their flight path according to coastlines, pigeons can accurately navigate long migrations.
How many hertz are in 1 Gigahertz?
1,000,000,000 Hertz=1 Gigahertz
How many hertz correspond to fifteen megahertz?
There are 15 million Hertz in megaHertz. It is spelled, "Hertz" because it was named after a person.
How many hertz can bats hear?
1,000 to 120,000 but sometimes 210,000 hertz
Where can one get a Hertz van for hire?
Hertz vans for hire can be found from many different resources. Some online websites that offer Hertz vans for sale include Hertz, Hertz on Demand, and Car Rentals.
How many meters in a hertz?
They aren't comparable. "Meter" is a length, while "Hertz" is a frequency.
How many hertz make up one gigahertz?
The hertz is named after Heinrich Rudolf Hertz who proved that electromagnetic waves did exist. The measurement of one gigahertz is the equivalent of 1,000,000,000 hertz.
The frequency of its sound wave determines its what?
The sensation of a frequencies is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
What part of a waveform describes a sound's frequency or pitch?
It depends upon how many oscillations per second. 50 oscillations per second = 50 hertz (hz).
What does frequency of 1Hz means?
Hertz, named after the German Physicist Heinrich Hertz, are the measurement of frequency, current, and electricity, their uses are common in many fields, sound waves, radiation, hertz are even used to represent the speed of your computer. Hertz come in 21 tiers of measurement - listed from smallest to largest: Yoktohertz Zeptahertz Attohertz Femtohertz Picohertz Nanohertz Microhertz Millihertz Centihertz Decihertz Hertz Dekahertz Kilohertz Megahertz Gigahertz Terahertz Petahertz Exahertz Zettahertz Yottohertz 1 hertz = 1 cycle per second (cps)
