The original sound is higher than the echo, because some of the energy of the original sound waves, and it is known that sound is the waves that pass through the physical medium, and the sound echo is a reflection of these sound waves reflected by surfaces that cannot pass through them, and through this article through The position of the clock, we will learn that the original sound is higher than the echo, because some of the original sound wave energy, please follow this article with us to the end.

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 the direction of propagation of sound waves it is the direction of their vibrations and humans can by nature hear sounds that fluctuate in its frequency range of 20 to 20,000 Hz otherwise they couldn’t.
The original sound is louder than the echo, because it is part of the energy of the original sound waves
Sound waves bounce off surfaces they can’t 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 generally better on flat surfaces than uneven surfaces, as it scatters sound waves, the time interval between emission and reflection of sound is estimated to be 0.1 seconds and the echo phenomenon is not limited to mechanical waves, but rather includes 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 anything that bounces.
Sound wave classifications
It is worth noting that Sound waves It is usually divided into three basic classifications, and this is according to its frequencies, and below we will mention these classifications, which are as follows:
- Auditory waves: These 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 above 20,000 Hz, as they are beyond the reach of the human ear and are used in different uses such as industrial and medical applications.
- Infrasound: These are sound waves with a frequency below 20Hz, which means that humans cannot hear or even hear them.
What are the properties of sound waves
There are a variety of characteristics of sound waves that distinguish them from other waves, and we’ll enumerate them here for you:
- Frequency The frequency of sound waves is the reciprocal of the period, measured in hertz.
- Cycle Time This is the time it takes to complete one complete cycle or vibration.
- Amplitude 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 two consecutive atoms or lower parts of a sound wave measured in meters.
- Repetition The frequency of sound waves occurs when they hit a surface that does not allow them to pass.
The use of sound waves
Sound waves have many uses and uses which we will mention to you as follows:
- Sound waves are used in communication where sound waves travel through the vocal folds and then through the air to be heard.
- Sound waves are used in sonar and radar.
- Sound waves are used to detect the 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 capture some animals such as bats.
Here we are at the end of our articleThe original sound is louder than the echo, because part of the energy of the original sound waves, where we have learned what sound is, as well as we have known the classifications of sound waves, what are their most important characteristics and uses.
