By keeping Directv I saved $120 and was given $200 plus a $20 credit. Here is how I look at it. My service for the next year will cost $768, but I can subtract out the $120 ETF, $200 Visa card and the $20 credit meaning my cost is $428 for 12 months or about $35.66 per month.ere is how I look at it.

See reference 1 for a scale of dB intensities. Conversation is listed at ~60 dB. normal talking is usually between 50-60 dB and yelling can be up around 80 dB's. Voice Decibel. dB is a measure of relative magnitude. dBA is a measure of sound volume relative to a reference audio level.
I can't figure out how to interpret my audiogram. I keep finding different standards for 'normal limits.' Some say it is 0-20 db, others 0-15 db. Some say it is 0-15 db for children and 0-25 db for adults.And yet others make it seem as though 0 db is the average threshold at all frequencies for 'normal hearing' young adults.he results themselves, however, fall in a bell-shaped curve, in exactly the same way that other human dimensions do (think average height, weight, age for example). The lower limits of what is considered normal gets influenced by how the information is going to be used.
