The original sound is higher than the echo, because part of the energy of the original sound waves, and it is known that the sound is the waves that pass through the physical media, and the sound echo is a reflection of these sound waves reflected from the surfaces that cannot pass through them, and through this article through The location of the clock, we will learn regarding the original sound being higher than the echo, because part of the energy of the original sound waves, follow this article with us to the end.
voice identification
Sound is defined as invisible mechanical longitudinal waves that propagate through physical media such as solids, air and gases, without which it cannot propagate, and this is also all that the ear perceives, so that the direction of propagation of sound waves is the direction of their vibrations, and humans can by nature hear sounds that fluctuate in its frequency range from 20 to 20,000 Hz otherwise it might not.
The original sound is louder than the echo, because part of the energy of the original sound waves
Sound waves bounce off surfaces they cannot pass through, and the original sound is usually louder than the echo, because some of the energy in the original sound waves has been absorbed.
Since sound resonance is an example of how waves interact with different materials, sound reflection is usually better on flat surfaces than on uneven surfaces, since it scatters sound waves, the time interval between sound emission and reflection is estimated at 0.1 second, and the echo phenomenon is not limited On mechanical waves, but rather include electromagnetic waves, such as the reflection of light on mirrors, where sound and light usually correspond to behavior, and in general the phenomenon of resonance is associated with everything that bounces off.
Classifications of sound waves
It is worth noting that Sound waves It is usually divided into three basic classifications, and this is according to its frequencies, and here below we will mention to you these classifications, which are as follows:
- Hearing waves: They are waves with a frequency between 20 and 20 thousand Hz, as they include all the sounds that the human ear can hear.
- Ultrasound: These are the waves with a frequency of more than 20,000 Hz, as they are located outside the range of the human ear, and they are used in several uses such as industrial and medical applications.
- Infrasound: These are sound waves with a frequency of less than 20 Hz, meaning that humans cannot hear or even feel them.
What are the properties of sound waves
There is a variety of characteristics of sound waves that distinguish them from other waves, and here we will enumerate them for you:
- Frequency The frequency of sound waves is the reciprocal of the period, measured in hertz.
- Cyclic time This is the time required to complete a full cycle or vibration.
- Amplitude The amplitude determines the intensity of the sound wave and the amount of energy carried by the wave and is measured in Pascals.
- Wavelength The distance between any two consecutive atoms or bottoms of a sound wave measured in metres.
- Repetition The frequency of sound waves occurs when they hit a surface that does not allow them to pass through.
The use of sound waves
Sound waves have many uses and uses that we will mention to you as follows:
- Sound waves are used in communication where sound waves travel through the vocal cords and then through the air for you to hear.
- Sound waves are used in sonar and radar.
- Sound waves are used to detect oceans.
- Sound waves are used to find underground resources in the earth.
- Sound waves are used to locate and explore oil wells in the ground.
- Sound waves are used to locate fish.
- Sound waves are used to determine location.
- Sound waves are used to catch some animals such as bats.
Here we come to the end of our articleThe original sound is louder than the echo, because part of the energy of the original sound waves, where we got to know what sound is, as we got to know the classifications of sound waves, what are their characteristics, and their most prominent uses.
