At what frequencies do advertisers concentrate the commercials sound?
At frequencies in which the ears are the most sensitive.
How many different types of sound waves 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.
What kind of sounds do you hear on bonfire night?
The crackling of a fire is the most prominent sound you will hear on bonfire night. You will also hear talking between those at the bonfire.
Which material transmits the most sound energy?
air is a good transmitter of sound energy. also metals are very good due to there metallic bonding properties. most materials are best at transmitting different frequencies, aka their resonant frequency.
Explain how do you hear?
The tympanic membrane, or eardrum, receives sound in the first step. It sends a ripple, a reverberation of the sound, across the malleus, incus, and stapes (the three smallest bones in the body), and into the cochlea. The cochlea reverberates into the auditory nerve, which carries to the brain and delivers the sound.
What is the maximum range of sound frequencies that human can hear?
most people hear frequencies between 20 and 20,000 Hz
Do all animals hear the same frequencies of sound as human do?
Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
An earthquake is a fairly quiet shaking of the earth?
For humans it is, because most of the sound is at frequencies too low for us to hear.
At what frequencies do advertisers concentrate the commercials sound?
At frequencies in which the ears are the most sensitive.
Do all animals see the same frequencies of visible light as humans do Do all animals hear the same frequencies of sound as humans do?
no bats and many marine animals can hear high frequency noises We can't. Most other animals can't
Can Labradors hear through doors?
Labrador Retrievers, like most dogs, have excellent hearing. They can hear any sound that you can hear, and many more in higher frequencies and lower volumes. If are able to hear something happening through a door, chances are your pooch can too.
What is the difference between frequency and pitch?
The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch
Why are children more likely to hear bats than adults?
Because children can hear higher frequencies, and a bat sound is usually very high pitched. A child may also not be able to hear it, if the bat has a particularly high voice. In theory, children can hear a maximum high pitch of 20,000Hz. This is only if the child's hearing is perfect, which, in most cases, it isn't. Basically, what I'm trying to say, is that as you get older, your ability to hear high pitched sound gets worse.
How quadrilateral sound like?
Quadrilaterals are geometric objects and for most people they make no sound at all. Only some synaesthetes may be able to hear quadrilaterals.
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.

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.
What is the maximum frequency which an ideal human can perceive?
Most people with 'normal' hearing can perceive sound up to 18,000 Hertz. The higher frequencies become less audible with age.
How is the vibrations that we feel related to the sound we hear?
Sound is a vibration that propagates as a wave. Generally speaking, if you can feel a vibration, you can't hear it - and vice versa. That's because you can only hear vibrations of 20 Hz (20 cycles per second) or more; but you are usually not able to feel anything, if it vibrates that quickly. Of course, most naturally-occurring sounds are a mix of different frequencies, so in some cases you may be able to both hear and feel, especially if the sound is very loud.
