Healthcare Clinic Patient Privacy and Sound Masking System

Many hospital environments can be extremely noisy, disrupting patients and causing privacy concerns. If patients are able to hear other peoples' discussions, they feel they might also be heard by others. As a result, patients may feel that they cannot fully discuss their issues with their caregivers. This not only affects the patients' health but directly violates the required safeguards that are mandated by HIPAA. As patient satisfaction and quality of care become a greater focus, hospitals are seeking ways to increase acoustic comfort and privacy. This speech privacy sound masking system provides an unobtrusive and consistent background sound, similar to airflow, and is designed to reduce the impact of distracting noise and mask confidential conversations. This sound masking system also dramatically contributes to patient satisfaction because it effectively promotes rest and relaxation. Ideal for patient rooms, doctor offices, emergency exam rooms, nurses' stations, hospital administration, main lobbies, waiting rooms, patient registration desks, and business offices.
Improve Medical Outcomes and Patient Satisfaction
Sleep is an important part of the recovery and healing process, but the noise from hallways, nurses’ stations, and surrounding rooms often prevents patients from getting the rest they need. Excessive noise and the lack of sleep are some of the main concerns that patients have. Not only does a noisy hospital environment disturb patient sleep, it weakens their immune system and impacts recuperation. Studies show that patients in rooms with sound masking find that it helps to shorten the time it takes to fall asleep and prevents unwanted noises from disrupting their sleep. Patients have reported they've slept better, felt it was quieter, and were more satisfied with staff care.
An All-in-One Solution for Speech Privacy
This Qt Patient Privacy System consists of a control module, two lighted privacy signs, and 12 direct-field sound masking emitters. The intuitive control module can be installed in a reception desk, in the nurses' station, or mounted to any wall. Once turned on, the emitters installed in the ceiling add a low level of background sound into the space that will make human speech less intelligible. Lighted privacy signs turn on to indicate the system is running, and let patients know that their conversations are being protected.
Easy to Retrofit into Existing Spaces
The Qt Patient Privacy System can be installed quickly and inexpensively in any medical office through Cambridge Sound Management's nationwide network of certified sound masking professionals. Privacy signs can be surface mounted, glass mounted, or mounted into a gang box, easily blending in with modern medical office décor.
Mounting Options
The control module can be surface mounted directly to the wall, flush mounted with the supplied box, or flush mounted to a suitable 4-gang electrical box (or 3-gang using EU/UK hardware). The privacy signs can be mounted on glass using the hider plate, surface mounted with self-adhesive tape, or mounted using a 1-gang box (North America NEMA or EU/UK types).
* The entire system is GreenSpec listed, consuming less than 7 watts of power. The system can help enable LEED v4 certification in the categories of acoustics and daylight harvesting.
