Nikki Clark and Colette Vossler-Welch, BS, are clinic assistants at Corvallis Hearing Center.Listing in this document does not constitute or imply endorsement by the Commission of any particular product, manufacturer, vendor or resource. Hearing loop assistive listening device Hear Here S+. ![]() He has served as a consultant for the Teen Transition Project of the Hearing Loss Association of America (HLAA), the American Bar Association access program, and the US Forest Service visitor center accessibility program. Leavitt, AuD, is an audiologist who owns Corvallis Hearing Center in Corvallis, Ore, and is the founder of the Oregon Association for Better Hearing (OABH), a nonprofit consumer test group for hearing aid users. In the meantime, this work-around is offered as an interim solution for those manufacturers’ products that continue to offer analog inputs.Ĭorrespondence can be addressed to HR or. ![]() It is preordained that, in the future, ALD manufacturers will offer an optical digital interface on all of their products. However, this work-around does allow hearing aid wearers to access today’s more advanced media systems without interfering with the listening enjoyment of others with normal hearing. It might be argued that down-converting a digital 5.1 surround optical signal from a television to a mono or stereo analog signal is not good audio practice. RCA to 3.5 mm stereo or mono adaptor (6 ft) Oticon ConnectLine TV adapter, Phonak TV Link, ReSound Mini Mic (pictured), Siemens Bluetooth transmitter, Starkey Surflink (which already has a digital optical input and does not require the analog conversion), Widex TV DEX, a Qlink Bluetooth transmitter, or Sennheiser wireless TV systems (sets 830, 840, IS 410, and R S120)ĭigital Optical Coax to Analog RCA Audio Converter AdapterīlueRigger Digital Optical Audio Toslink Cable (various lengths available) All parts are available online from Amazon and many other audio retailers. A parts list of the necessary adaptors is given in Figure 2 for the digital to analog conversion. The wiring diagram for this is also shown in Figure 1. This connection allows other family members with normal hearing to continue to use the surround system with high-fidelity loudspeakers. Wiring diagram for ReSound Mini Mic or other analog ALD to 5.1 Surround System.įor households with surround sound systems, the HDMI output from the digital cable box is then fed to an amplifier, which might be either an AM/FM surround sound system or digital mixer/amplifier. This digital to audio conversion allows the person with hearing loss to use the hearing aids as the wireless receiver device with their respective analog transmitters.įigure 1. They improve what is known as the speech to noise ratio. They separate the sounds, particularly speech, that a person wants to hear from background noise. Essentially they are amplifiers that bring sound directly into the ear. This would also include Sennheiser wireless TV systems (sets 830, 840, IS 410, and RS 120) and older TV Ears. ALDs (assistive listening devices) are personal amplifiers that are used to increase volume in face-to-face and small group conversations. Assistive Listening Systems (ALSs) are sometimes called Assistive Listening Devices (ALDs). In this diagram, the digital output is converted to an RCA analog output, which can interface with any number of analog devices including but not limited to an Oticon ConnectLine TV adapter, a Phonak TV Link, a ReSound Mini Mic, a Siemens Bluetooth transmitter, a Starkey Surflink (which already has a digital optical input and does not require the analog conversion), a Widex TV Dex, or a Qlink Bluetooth transmitter. As such, analog ALDs cannot interface directly with the television.įortunately, there is an inexpensive work-around, as shown in Figure 1. wireless, and compatible with a persons digital hearing aids. This is becoming increasingly problematic as many of today’s televisions offer only digital audio outputs. Assisted Listen Devices (ALD) Sonic Shaker Portable Alarm Clock Think Labs One Digital Stethoscope Clarity Corded (E814) and Cordless (703HS) Amplified Phone. This is because the microphone of the assistive listening device is placed close to the. Most assistive listening devices (ALDs) continue to accept only analog inputs. Today, consumer and professional audio and hearing instrument science has gone digital with one important exception. Leavitt, AuD, Nikki Clark, AND Colette Vossler-Welch, BS A practical work-around to many popular ALD products. ![]()
