What sets Phonak's Slim apart from many other Bluetooth-enabled hearing aids is the universal compatibility with Apple iOS and Android devices. This allows for hands-free calls directly to your ...
While many hearing aids are more geared towards iOS, the Phonak Slim allows both Android and iPhone users to make hands-free phone calls. The Slim also has onboard tap control.
Alexa-powered Echo devices can also make phone calls, either to numbers in your contact list (which can be imported into the Alexa app) or any number you ask Alexa to dial. One exception: 911.
These devices are frequently used to improve the signal-to-noise ratio (SNR) in different situations. All Assistive Listening Devices (ALDs) consist of a transmitter sending a person's voice or another audio source to a receiver, which subsequently distributes the sound uniformly in environments such as theaters, churches, or even directly to ...
Although research is limited, it suggests that increased exposure to loud noise through personal listening devices is a risk factor for noise induced hearing loss. [ 35 ] [ 36 ] A systematic review of adolescents and young adults reports that over half of the research subjects had been exposed to sound through music exposure on personal devices ...
Sound masking is the inclusion of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Sound masking is not a form of active noise control (noise cancellation technique); however, it can reduce or eliminate the perception of sound ...
Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather than a power source. Active noise canceling is best suited for low frequencies. For higher frequencies, the spacing requirements for free space and zone of silence techniques become prohibitive.
Modern over-the-ear headphones offer incredible sound and impressive noise-cancelling, often for a surprisingly low price. (Photos: 1More, Soundcore, Sony)
