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.
Loudness or amplitude is measured in decibels and it is marked or notated using dB to designate decibels. Keeping in mind that at 85 dB hearing loss can begin, normal everyday conversation is at approximately 70 dB and loud talking is about 90 dB.This is one of the reasons why loud and boisterous people bother us so much.oudness or Amplitude â Science, specifically audiology, knows that the difference between the threshold of human hearing (0 dB) and the threshold of pain (120 dB) and hearing loss occurs at approximately 120 decibels.
