Sound level for our vacuums is a pet peeve of mine, so I make it a point of measuring. With my uncalibrated iPhone App I measure my house on a typical day at 44dB. We're quiet. This vac kicks the noise up to 75-77dB from a yard or two away. The pitch, overall, is not too bad, except for a bit lower volume, higher frequency sound I find annoying. This isn't a quiet vac. Ask the BB store support to fire one up for you. I should note that various vacs of the same model might have differing volumes and pitches.
