Sound Ppt 01 Pdf The bit rate refers to how many bits are used to store sound levels at each sample, with more bits distinguishing more levels but also increasing file size. view online for free. Physics – sound learning objectives core •describe the production of sound by vibrating sources • describe the longitudinal nature of sound waves • state that the approximate range of audible frequencies for a healthy human ear is 20 hz to 20 000 hz • show an understanding of the term ultrasound.
Sound Powerpoint Presentation For Grade 7 Pptx Cambridge igcse (0478 0984) 1.2 representing sound free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. Vibrations in the air create waves of pressure that are perceived as sound. these vibrations are passed on from one air molecule to another and eventually reach our ears. Digital representation of sound data representation real sound • sound in the real world is made up of combinations of different frequencies • a sound wave is a combination of these different frequencies:. A powerpoint going over the content for the aqa computer science gcse spec. the topic is on sound representation and covers everything the students should know to be.

Sound is really tiny fluctuations of air pressure units of pressure: n m2 or psi (lbs square inch) carried through air at 345 m s (770 m.p.h) as compressions and rarefactions in air pressure properties of waves wavelength ( ) is measured from crest to crest or trough to trough, or upswing to upswing, etc. To help you plan your year 10 computer science lesson on: representing sound, download all teaching resources for free and adapt to suit your pupils' needs. the starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in pdf format. Understand how sound is sampled and stored in digital form. be able to represent a short sound file in binary. explain how sampling intervals and resolution affect the size of a sound file. explain the trade off between file size and the quality of playback.
