I am trying to set up a relatively easy method to measure acoustic noise
within MRI scanners, as close to the bore as possible.
I have come up with two scenarios, wondering if anyone has any experience
with either?

1] measure noise using an MRI-compatible sound level meter, such as (

)

2] use a calibrated microphone, extension cable threaded through a wave
guide and an external integrating sound level meter, such as instruments
from Casella Cel (casellausa.com)

Thanks in advance!

Fatima
