A siren is producing a tone of frequency 10000 Hz, and a handheld decibel meter (like the one I use in class) is reading 20 dB. We've talked in class about how your perception of qualitative loudness (in phons) does not always match exactly with the meter. Using Fig 6.12 o...

Suppose a person is going to be exposed to a steady tone of frequency 8000 Hz all night (perhaps arising from noisy electronics in a nearby room. ) If this person wants their perceived room loudness level to be a very quiet 10 phon (in order to sleep easily), what is the maxim...
