Noise development

By switching the currents in the gradient coils for imaging purposes,
the mechanical forces lead to noise development (humming,
knocking noises) during the MR examination which can exceed
99 dB(A) in the bore.
 CAUTION
Noise development during the MR examination!
Injury to patient and people in the examination room
(hearing impairment)
◆ Provide the patient with appropriate hearing protection that
lowers noise to at least 99 dB(A).
◆ Mandatory provide anesthetized or unconscious patients with
hearing protection. Ear protection for these patients should
not be omitted even at moderate sound levels.
◆ Ensure that personnel and accompanying persons in the
examination room wear hearing protection during the
examination that lowers noise to at least 85 dB(A).
◆ For required level of hearing protection, see:
Manual, Technical data: Hearing protection
protection devices must provide the required level of sound
attenuation.
Adequate attenuation levels can be achieved by using, for example,
ear plugs. Ear plugs offering sufficient hearing protection can be
found in the Siemens Accessories catalog.
The standard Siemens headphones are intended for communication
with the patient and can be used in combination with ear plugs.
