The OITC is the difference, rounded to the nearest decibel, between the value 100.13 and the logarithmic sum from Step 2. Note this value of 100.13 is the to 2 decimals rounded logarithmic sum of the A-weighted reference spectrum. The entire process can be conveniently expressed in a …

If you have a calculator with a log button, you can confirm that the log10 of 200 is approximately 2.3, which means that 102.3 = 200. There are several methods that can be used to obtain the logarithm of a number that is not a whole number power of ten, but the simplest by far is to use a hand calculator that is equipped with a log function.

A T-Test calculator was used to calculate a t. 7-value of 2.744, with a p-value of less than 0.05 for the changes between the first two baseline tests. Therefore, between the first two baseline tests, it can be said that, with 95% confidence, there was a statistically significant decrease in the rats’ responses.

Use the calculator to find the point of intersection of y = 4x+3 and y = 7. Discuss this alternate process for solving the equation 4x+3 = 7. Compare the decimal answer to the decimal equivalent of the exact answer above, and discuss the difference in an exact answer and decimal approximation. (Solution: ) …

The decibel is the unit used to measure the intensity of a sound. The decibel is named after Alexander Graham Bell who did much work in the area of sound and loudness. Bell discovered that to obtain a sound that seemed twice as loud as another sound, the intensity (how much sound energy per unit area per second hits the eardrum) of the sound ...

Any positive number can be used as the base for an exponential function, but some bases are used more often than others. We will see in the remaining sections of this chapter that the base 2 and 10 are convenient for certain applications, but the most important base is the number denoted by the letter
