6. where t is the number of years since 1960. determine the estimated world population in the year 2020 since 1960, the growth in world population (in millions) fits the exponential function a(t) 3100e 0.0166t 7. the loudness of sounds is measured in a unit called the decibel. to do this, a very faint sound, called the threshold sound, is assigned an intensity lo. if a particular sound has intensity i, then the decibel rating of this louder sound is given by db rating = 10 find the decibel rating of a human voice if the intensity is 630,957,34410. round to the nearest whole number

To understand the decibel scale. the decibel scale is a logarithmic scale for measuring the sound intensity level. because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in w/m2 changes by a multiplicative factor. the number of decibels increases by 10 for a factor of 10 increase in intensity. the general formula for the sound intensity level, in decibels, corresponding to intensity i is β=10log(ii0)db, where i0 is a reference intensity. for sound waves, i0 is taken to be 10−12w/m2. note that log refers to the logarithm to the base 10. what is the sound intensity level β, in decibels, of a sound wave whose intensity is 10 times the reference intensity (i.e., i=10i0)?

The decibel is the unit of sound level, which is a convenient way of representing the large range of sound intensities that the ear can detect. from the definition of the decibel we can see that increasing the sound intensity by a factor of ten results in:
