CSD 1025 ~ HEARING SCIENCE Laboratory – Sound Measurement The object of this lab is to extend your knowledge of scientific notation to logarithms and, then, the computation of decibels. Thereafter, we’ll look into some practical applications of decibels and related concepts. A. Decibel and Related Work Problems As with the more basic concept of scientific notation and with certain problems in basic physics, it is helpful to get a little experience with actual numbers and calculations, rather than relying on purely conceptual approaches in your learning of the course material. Following the orientation given by your lab instructor, try your hand at the following problems. 1. Determine the logs of the following numbers: a. 10 b. 2 c. 5 d. 11,000 e. 5300 f. 86.5 g. 123,456 2. Determine the intensity levels of the following measured acoustic intensities given a reference of 10 -12 w/m 2 : a. 12 w/m 2 b. 0.32 w/m 2 c. 0.00003 w/m 2 d. 6 w/m 2 e. 1000 w/m 2 3. Determine the sound pressure levels
