For those whose hearing disorder requires the use of a hearing aid, watching television can be a burden. Many hearing impaired people say they struggle to understand speech on the small screen, even after purchasing modern hearing aids. Part of the reason is that hard of hearing individuals typically require a more positive signal-to-noise ratio to have exactly the same speech recognition as those with average hearing.
Connection challenges to TVs with only digital sound outputs
Assistive technology plays a crucial role in the hearing healthcare of people who cannot handle or afford hearing aids. Assistive listening devices help address communication issues by amplifying sound levels and are generally stand-alone tools without the need for hearing aids. Many options exist, including personal listening systems, telephone amplifying devices and TV listeners.
Those who have already gone digital will experience difficulties when trying to link their TV listeners to television sets with only digital sound outputs. TVs and ALDs are typically wired together via the standard CATV cable. It supports two ranges of signal: an analogue band and a digital band. The former can be tuned directly by most TVs and listening devices that support the analogue transmission standard; the latter will require users to purchase set-top convertors. Besides cable connection could be slow. The cables and connectors on the rear of a TV can be daunting, and each producer uses a different layout.
Locking onto a digital picture can be annoying, time-consuming and quite often a fruitless effort. Occasional loss of signal means a temporary blank screen and drop-off in audio. The more frequent the signal losses, the less watchable the programme, since the flow of dialogue or events is lost. With some channels, the digital picture is steady, unless people move around inside the room, which causes the loss of signal. And even when the picture does come in, it can break up with an agonizing frequency, taking the sound along with it and often making a programme unwatchable.
The new CL7150 as the first TV headphone system to connect with Digital TVs
At least 8.7 million people in the U.K. suffer from mild to moderate hearing loss. Their options are limited, and hearing aids can cost a fortune. Many patients continue to have problems picking out voices in loud settings.
Geermarc has recently launched the first Geermarc CL7150 wireless TV listener to offer connection to Digital TVs. The device isolates and amplifies voices, thereby providing clear sound gain. It is perfect for watching television and other activities associated with communication as it eliminates unwanted background noise and magnifies nearby voices.
Designed to offer an independent tone and volume control of TV volume levels, Geermarc CL7150 works with zero disturbances to volume for others. There are a few of these devices on the market, however this is the only one that fits to Digital TVs without Red and White audio outputs or SCART. It features a balance option to suit to either left or right ear preferences. The TV headphone system ensures up to 10 hours continuous use.
