The PrivacyCard™ Babble Noise Generator

Babble noise, engineered recordings of live voices similar to the background noise at your local coffee shop, offers a higher level of efficiency when camouflaging speech. This allows you to use lower masking levels while ensuring the same amount of privacy. In open offices, overheard conversations are often cited as the main source of distraction because ignoring a person talking is a difficult task for the human brain, especially when you can clearly hear the conversation. An excellent way to reduce the annoyances of intelligible speech is to mask it using natural noises with the babble noise-generating PrivacyCard™ USB sound masking card.

Pure Resonance Audio’s trusted industry professionals partnered with a former Roland® PHD Sound Engineer to take the mystery out of sound masking by creating an affordable product that’s easy to operate and uses a universally familiar interface. The Pure Resonance Audio PrivacyCard™ is a USB babble noise generator that’s compatible with most USB ports enabling you to plug in and play with a USB mixer or mixer amplifier. Our frequency-shaped waves of ambient noises focus on the frequencies you want to effectively block, this ensures higher efficiency and quieter masking levels to achieve comfort, privacy, and focus.

Sound masking is an effective productivity tool that also offers speech privacy in the form of sound. Ambient noise is proven to protect private conversations and boost productivity, as well as creativity, by helping to reduce unwanted noises, eliminate distractions and prevent outsiders from overhearing sensitive information. Corporate offices, doctor offices, therapists' offices, law offices, hospitals, pharmacies, hotel lobbies, church offices, and generally open office floor-plans often benefit from sound masking devices. The added noise covers existing sounds in the area making the atmosphere more acoustically comfortable and overall providing a more pleasant and private place for employees, customers or patients.

An extremely simple and versatile solution, the PrivacyCard™ also allows customers to mix our proprietary babble noise masking with their favorite music. Create the ultimate private environment with sound masking and background music capabilities in any bank or financial organization, military or government agency, law enforcement building, medical facility, educational institution, law firm or any other business.
