Because of the enormous nonlinearity of the ear in sensing pressure waves, a nonlinear scale is convenient in describing the. Technical information, teaching suggestions, and related resources that complement this Concept Builder are provided on the Notes page. Sound - Decibel, Frequency, Amplitude: The ear mechanism is able to respond to both very small and very large pressure waves by virtue of being nonlinear that is, it responds much more efficiently to sounds of very small amplitude than to sounds of very large amplitude. Given input and output levels, subtract them in order to find the gain. Given an input level, simply add the gain to it in order to find the output level. Learners and Instructors may also be interested in viewing the accompanying Notes page. When both circuit gains and signal levels are specified in decibel form, analysis can be very quick. However, the 12 different groups of questions can be viewed and printed. There is no need for an activity sheet for this Concept Builder. Users are encouraged to open the Concept Builder and explore. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress. The learner must use this information and an understanding of deciBels in order to determine the deciBel level of Sound Source B. There are 36 total questions organized into 12 different Question Groups and spread across three difficulty levels. The greater the amplitude of vibrations of the particles of the medium, the greater the rate at which energy is transported through it, and the more intense that the sound wave is. Learners are told the deciBel level of Sound Source A and are told that Sound Source B is 10 n times more or less intense. Sound Intensity and Distance The amount of energy that is transported past a given area of the medium per unit of time is known as the intensity of the sound wave. The Decibel Scale Concept Builder sharpens a learner's understanding of the logarithmic nature of the deciBel scale. Concept Builders » Waves and Sound » Decibel Scale When you need to get more specific than 'loud' or 'quiet' when referring to volume, use DECIBELS to describe the power of your sound wave Watch to find out.
