A level Sound and Hearing Quizzes.

(Sound and Hearing Quizzes for A level  students , GCE, and GCSE candidates)

To begin, Sound is very essential to we humans, it is important because it can tell us about character, place, and time, it informs us and moves us in ways visuals can't, and because certain combinations of sound and visuals can evoke what neither can do alone. It's also potentially important because it can help to determine what we see after all these are fulfilled, we can say we heard sound.

is a vibration  that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. It is created when something vibrates and sends waves of energy (vibration) into our ears. The vibrations travel through the air or another medium (solid, liquid or gas) to the ear. The stronger the vibrations, the louder the sound. Sound changes depending on how fast or slow an object vibrates to make sound waves.  
Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics:
- Time-Period
- Frequency and
-Velocity or Speed.

Note that,  The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. 

Hearing is the ability to perceive sounds by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear.
The process of hearing
    Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds. Loudness is the perception of the intensity of sound. 

       These quizzes are very important as it will test how well you know the topic sound, which you get to experience daily. The ability to hear enables us to connect to the world for many very important, even vital, reasons. Most importantly, hearing connects us to people enabling us to communicate in a way that none of our other senses can achieve.
