I have sometimes wondered about the sounds we hear in our daily lives, and this is what I would like to discuss.
In the midst of our casual lives, I suddenly wondered why sound is generated and how it reaches our ears. And how does it reach our ears? I wondered.
In the first place, sound is created by air vibrations that form waves, which reach our ears and are then heard as sound.
Sound travels 340 meters per second. This is when the temperature is 15 degrees Celsius, though.
I am sure you have experienced this, but there are times at a fireworks display when the sound is heard seconds after the fireworks go off, right?
If you hear the sound after 3 seconds, the fireworks are set off 3 seconds x 340m = 1020m away. This will be
This will tell you how far away you are from where the fireworks are now.
Sound waves, as explained earlier, are air vibrations that turn into waves, which then reach our ears and turn into sound.
The question arises, then, why do we hear higher or lower pitched sounds?
It depends on the shape of the wave.
High pitched sounds have fast wave periods and narrow intervals.
Lower tones have a slower wave.
This period is called frequency, and the lower the sound, the lower the frequency value. Conversely, the higher the sound, the higher the frequency.
Range of frequencies that people can hear
The range of frequencies that people can hear is generally said to be 20 Hz to 20 kHz (20,000 Hz).
So, people perceive sound within this frequency range.
In fact, when we play a piano or a guitar, we perceive a difference in sound because of the quantity, or frequency, of the waves that the instrument vibrates.
Anything that vibrates always produces sound.
What is important in music production
I mentioned frequency earlier, and this term frequency is a very important thing to know when mixing and mastering music.
When you record various instruments, their tones are made up of various frequencies.
If the frequencies collide when they are combined into one, there is a phenomenon where sound waves collide and are not heard.
This is called “masking. Simply put, masking is a phenomenon in which sounds collide with each other and are drowned out. The sound that is supposed to be there is drowned out, and thus cannot be heard.
Masking” will be explained in detail in another article, so please skip over it here.
The three main elements of sound
Sound has three components: loudness, pitch, and timbre.
These are the three main elements of sound.
When these are combined, they produce various sounds that we perceive as different from each other. The loudness of sound is expressed in dB (decibels).
The louder the decibel, the louder the sound, and the louder the decibel, the louder the sound. Next, pitch is the frequency mentioned earlier. People perceive pitch by how high or low this frequency is.
Finally, timbre is the shape of the waves, which people perceive as different from each other.
Summary of sound
In this issue, I have been thinking about sound.
We usually listen to sound without thinking about it, but it is very deep.
However, for those who do not produce music, there is no need to think about it, but for those who handle and produce music, like us, this sound is very important.
The three main elements of sound are essential knowledge, and I will explain them in detail in another article.
See you soon.
