Pharmacy Patient Privacy and Sound Masking System

The pharmacy is a public place where personal and confidential information is constantly being shared and patient privacy is a big concern. Imagine a pharmacist is in the back, on the phone talking to the doctor’s office and a technician is typing information about a new patient who has come in. The patient is waiting at the counter and there's a long line of patients waiting to fill their prescriptions. While this is going on, the technician has a question and directs the question to the pharmacist standing on the other side of the pharmacy regarding the patient’s medication. Without hesitation, the technician yells out to the pharmacist about the patients' medication. The pharmacist, who is on hold with the doctor’s office yells back and answers the question. The patient now feels embarrassed and upset. The pharmacist is required, just like any other health care provider, to keep a patient’s profile managed in order to protect the rights of the patient. With this cost-effective sound masking system, you can help protect their medication information, address, phone number, insurance information, driver’s license numbers, social security numbers, and other private information. With keeping patient information private and confidential, it is indirectly allowing the patient to build trust for the pharmacy and pharmacist.

 An All-in-One Solution for Speech Privacy

This Qt Patient Privacy System provides noise cancellation by making human speech less intelligible and consists of a control module, two lighted privacy signs, and 8 direct-field sound masking emitters. The intuitive control module can be installed behind the counter, in an office, or mounted to a 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.
