SOUN D by: Nick & Julian

How Sound Works :-] Sound is made when two things touch. Sound travels in waves. E.x when a drumstick hits the face of the drum it vibrates/moves.

Volume Volume is how loud or soft a sound is. E.X how loud or how soft your TV

Pitch A pitch is how high or low a sound is. E.X a long string has a low pitch and a short string has high pitch.

Decibels Is the measurement of sound. A dishwasher is 80 dB loud.

Frequency Frequency is the number of vibrations per second. A sound with a high pitch has a high frequency.

QUIZ What unit measures sound???? Decibels What is the loudness of sound???? Volume

LET’S GO TO THE FUTURE OF SOUND
