Hello my dear learner! You may be curious as to how sound is made. As living organisms, we are surrounded by many sounds. Some are low but some are high. Some are soft but some are loud. When we sing a song or when we tap on objects, we produce sounds. Sound enables us to communicate with one another. In order to have a healthy communication we need to consider how it is produced and its basic characteristics. These characteristics will be explained as we go along with our discussion.
