of 1.0 x 10 -2 W/m 2 has a decibel rating of 100.0 dB. Using Figure 1, this decibel rating can be combined with the frequency of 200 Hz to determine the phon rating. The coordinate point with values of 200 Hz and 100 dB lies above the 90 phon line. A reasonable estimate is that it is an approximately 100 phon sound.
How to Become a Forensic Science Technician. Forensic science technicians typically need at least a bachelorâs degree in the natural sciences, such as chemistry or biology. On-the-job training is usually required for both those who investigate crime scenes and those who work in labs.
