How do humans use sound energy?
The simplest and most obvious use of sound energy is for hearing. Humans can hear frequencies between about 20 Hz and 20,000 Hz. Another way that we use sound waves to learn about our surroundings is SONAR (short for Sound Navigation And Ranging), which is used to map objects on the ocean floor.
What is the purpose of audio in life?
The following are the importance of sound in our lives: It helps us to communicate with others. By sound, we can understand the context of the words spoken. Sound can help people to protect themselves from danger such as the sound or horn of the train and other vehicles warn people to give way etc.

Without sound we wouldn’t hear and therefore wouldn’t speak. Of course animals can’t speak (human talk), but they can still communicate just as effectively. By grunting, crying, screeching etc they can communicate across vast distances, conveying important messages that may be critical to their wellbeing and survival.

When we hear sounds, our auditory system processes them and allows us to perceive or experience them – making sounds and noise subjective. What appeals to some may repel others. What soothes and calms, may be distracting and intolerable for someone else.
How can sound waves kill you?
A big enough wave will ‘drown’ you with its pressure. The human eardrum picks up vibrations as pressure waves move the thin flap of skin back and forth. However, if the sound is too loud or the pressure too great, the eardrum can vibrate so violently that it ruptures. The same goes for lungs.
Can you die from a sound being too loud?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.
