Insights & Solutions

As part of the noise toolbox, in this issue brief you will learn about how excessive noise can negatively impact patients and staff in the hospital environment, ways to improve patients’ perception of sound, and low-cost, medium-cost, and high-cost design strategies that can reduce noise.

This list of resources is made of up of articles, books, policies, organizations, and more, related to noise  Use this list to learn more about this topic.

HCAHPS scores related to noise in the hospital environment are typically among the lowest. Acoustic intervention packages implemented by healthcare organizations are often a combination of built environment and operational measures.  

The following are compiled from research literature, case studies, interviews, and other materials to provide an overview on the topic of noise.  

This tool provides healthcare designers and professionals with ideas on how to address the issue of noise in facility design.

Learn about: how St. Mary's Hospital targeted noise reduction goals for their cardiac care unit, about onsite sound measurements that informed material selection, and about design changes that resulted in reduced noise from the highest sources of sound.

Learn about: the impact of noise on both patient and staff outcomes, about the methods the research team used to evaluate noise levels, and the difference between patient and staff perceptions of noise sources.

In the ongoing battle to reduce noise in hospital patient units, much attention has been paid to the floor and the ceiling. Over the years, several case studies have shown that sound-absorbing ceiling tile and carpet can help significantly reduce excess noise on a unit. But what about the walls?

The issue of excessive noise in healthcare facilities is indeed complicated. Patients need a calm, peaceful environment in which to heal, and loud noises certainly are at odds with that concept. While architectural and design choices can be made to lower the general noise level -- high-performance sound-absorbing materials in floors, ceilings, and walls are examples -- perhaps the most important and effective step a healthcare organization can take is to create a “culture of quiet” among its staff on all levels.

For many years, carpet was considered a no-no for use in most hospital settings beyond waiting areas. The most oft-cited reason was cleanability, as well as a perceived added difficulty for caregivers pushing carts and other wheeled equipment.

However, with the growing awareness of the noise issue in hospitals—including the potential financial repercussions, based on the HCAHPS system and the reimbursements tied to it—carpet is getting a second look in some facilities looking to decrease overall noise levels.
