Determining Change In Blood Pressure Due to Environment and Loudness (DECIBEL(S))
DECIBEL(S): Determining Change In Blood Pressure Due to Environment and Loudness
Determine the effects of environment and sound on initial and average triplicate screening blood pressure done according to clinical practice guidelines with an automated device.
Standardly obtained blood pressures obtained in a noisy, busy, public space will be higher than attended blood pressures obtained (1) in the same environment but with earplugs to minimize sound and (2) in a quiet, private space without surrounding activity.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Inside private quiet1, Inside public loud, Inside public quiet, Inside private quiet2
The order of noise/environment for participants randomized to this arm will be: Inside private quiet1, Inside public loud, Inside public quiet, Inside private quiet2 |
Each participant will have 4 sets of 3 blood pressure measurements taken.
The participants will be randomized to the order in which the level of noise in their environment changes and whether they are in a public or private setting prior to each set of measurements.
