Sound 1
This is using the reflection or echoes of ultrasound to determine location.
What is echolocation?
Sound waves are this type of wave.
What are mechanical waves?
The SI unit of intensity of a sound is measured using this unit.
What is decibel?
This is how sound begins.
What is with vibrating matter?
The speed of sound is dependent on these factors.
What is density, temperature, and water vapor content?
In comparison with air, sound travels faster in this type of matter.
What are solids or liquids?
Intensity is a function of these two factors:
What are the amplitude of the sound waves and how far they have traveled from the source of the sound?
These are the three parts of the ear.
What are the outer, middle, and inner ear?
Sounds with frequencies below 20 hz are referred to as this.
What is infrasound?
Sound waves travel in this direction.
What is all directions?
This occurs when an object vibrates in response to sound waves of a certain frequency.
What is resonance?
Any defective or damaged part of the ear can result in this.
What is deafness?
Sounds with frequencies above 20,000 hz are referred to as this.
What is ultrasound?
The frequency of a sound determines this, which is also referred to as how high or low a sound seems.
What is pitch?
The inner ear’s function is this.
What is to turn vibrations into electrical pulses sensed by the brain?
This refers to the measure of the amount of energy in a sound wave.
What is intensity?
This is the transfer of energy from a vibrating object in waves which travel through matter.
What is sound?
The ear drum is in this part of the ear.
What is the outer ear?
The middle ear’s function is primarily this.
What is to amplify sound and channel it to the inner ear?
This technology uses sound waves in water to determine the distance and shapes of objects inside of water.
What is sonar?
The use of ultrasound to make pictures of structures inside something is known as this.
What is ultrasonography?
The frequency of a sound is measured using this SI unit.
What is a hertz?
In comparison with liquids, sound travels slower in this type of matter.
What are gasses?
These are three properties of sound.
What are speed, loudness, and pitch?
Sound waves can be slowed down in a medium by doing this.
What is cooling it?
