This article presents the results of a noise survey at Johns Hopkins Hospital in Baltimore, MD. Results include equivalent sound pressure levels (L(eq)) as a function of location, frequency, and time of day. At all locations and all times of day, the L(eq) indicate that a serious proble...
The bars in the Figure represent the comprehensive range of data in the eight hospitals for similar locations. The levels of the midrange frequencies are more than 10dB higher than the previously documented results. While we do not yet fully understand the source of this additional noise, we ...

In fact, a new study by acoustical engineers at Johns Hop- kins University found that hospital noise levels have increased steadily over the past 50 years. Since 1960, average daytime hospital sound levels have risen from 57 deci- bels to 72 dB, while average nighttime levels have jumped ...
Initial evidence on noise exposure during different surgical procedures at the Johns Hopkins Hospital (Unites States of America) demonstrates that the noise exposure in neurosurgical, urologic and gastro-intestinal surgeries ranges between 62 and 65 dBA. These noise levels in visceral surgery are ...

Cells of the immune system are present in the adult cochlea and respond to damage caused by noise exposure. However, the types of immune cells involved and their locations within the cochlea are unclear. We used flow cytometry and immunostaining to revea
(ICU) in a public hospital in Muscat city, Oman. Self-administered questionnaire was randomly distributed among respondents using both online and field survey approach to ascertain annoyance, health effects, and potential risks associated with exposure. The study found that 24-h noise levels (LAeq)...
