Improve patient speech privacy and create a more comfortable healthcare environment with the Cambridge Qt Patient Privacy Sound Masking System. Designed for doctors' offices, hospitals, clinics, urgent care facilities, reception areas, waiting rooms, exam rooms, and pharmacies, this system helps reduce the intelligibility of nearby conversations by introducing a carefully controlled level of background sound. The package includes eight direct-field Qt sound masking emitters, a wall-mounted control module, two illuminated privacy signs, and the necessary installation cables and mounting accessories. With coverage for spaces up to 800 square feet, the system provides an effective solution for supporting patient confidentiality and minimizing distracting conversations.
The Qt Patient Privacy control module manages the system's direct-field sound masking output, providing adjustable masking levels through an integrated LCD display and front-panel controls. It operates as a single-zone controller with two emitter cable runs and four non-correlated masking sources, helping distribute consistent background sound throughout the covered space. Independent ramp-up and ramp-down settings allow gradual transitions when activating or deactivating masking. The module can be wall-mounted, installed using the supplied mounting accessories, or integrated into a compatible electrical box for a clean, professional appearance. The system also supports an audio input for compatible music or paging sources.
The eight included Qt emitters are compact ceiling-mounted sound masking devices designed to introduce low-level background sound directly into the occupied space. Each emitter features a 1.25" driver, approximately 170-degree conical dispersion, and four-channel automatic sequencing to help minimize phase interference between neighboring emitters. Built-in attenuation settings of 0 dB, -3 dB, -6 dB, and -9 dB allow localized adjustments for different acoustic environments. The emitters feature RJ45 input and output connections for convenient daisy-chain installation using the included plenum-rated cables. With a compact white enclosure and ceiling tile mounting ring, the emitters integrate discreetly into professional healthcare environments.
The two included illuminated privacy signs provide a visible indication that the sound masking system is operating. Designed for placement near waiting rooms, reception desks, exam rooms, and other areas where confidential conversations occur, the signs help communicate the facility's attention to patient speech privacy. They receive power from the control module through the included 50-foot plenum-rated cables and can be installed using compatible single-gang electrical boxes, surface mounting accessories, or glass mounting hardware.
Installation Note: The included eight-emitter system supports spaces up to 800 square feet under suitable installation conditions. Actual speech privacy performance depends on room acoustics, background noise, emitter placement, and system adjustment. Sound masking can support an organization's patient privacy practices but does not independently guarantee HIPAA compliance or prevent every conversation from being overheard. Additional mounting hardware may be necessary for ceiling types other than standard acoustic ceiling tile.
