Sound

In my essay about sound, I am going to explain how different forms of sound are created, how they are heard, what a frequency is, how certain vibrations can decide the pitch, loudness and frequency of a sound wave. I am also going to explain how music is created, how every note has a different frequency, that harmony is very important when making music. I am also going to tell you about sound recording, replaying …

…and speakers. I hope now you have a better idea of how sound is made and how we can hear it. How every sound wave has its own frequency. How music is arranged and when listened to it can create certain emotions. How there are many ways of recording sounds. How it's possible for us to replay music by pressing one button. The difference between analogue and digital and the difference between microphones and loudspeakers.
