EDAC Acoustics and Sound Control in Healthcare Design 1

Question 1

What is the primary unit used to measure sound pressure levels in healthcare acoustic design?

Accepted Answer

Decibel (dB)

Answer

Decibels (dB) measure sound pressure levels and are the standard unit referenced in acoustic performance criteria and healthcare design guidelines.

Question 2

According to World Health Organization guidelines, what is the recommended nighttime noise level in hospital patient rooms?

Accepted Answer

35 dB(A)

Answer

WHO guidelines recommend nighttime hospital patient room noise not exceed 35 dB(A) to protect patient sleep and support recovery.

Question 3

Which wall design strategy is most effective at preventing sound flanking between adjacent patient rooms?

Accepted Answer

Building walls that extend to the structural deck above the ceiling

Answer

Walls extended to the structural deck close the flanking path above suspended ceilings, providing the highest level of sound isolation between adjacent spaces.

Question 4

In the context of healthcare acoustic design, 'speech privacy' refers primarily to which of the following?

Accepted Answer

Prevention of patient conversations from being understood by unintended listeners

Answer

Speech privacy ensures that confidential patient conversations cannot be understood outside the intended space, supporting HIPAA compliance and patient dignity.

Question 5

Which primary design and construction reference standard includes specific acoustic performance requirements for healthcare facilities?

Accepted Answer

FGI Guidelines for Design and Construction of Health Care Facilities

Answer

The Facility Guidelines Institute (FGI) Guidelines are the primary reference for healthcare facility design and include specific acoustic criteria for various room types.
