Miracle-Ear, Inc. is a hearing aid company consisting of a network of franchised and corporately-owned retail outlets. The company is a subsidiary of Amplifon, the worldwide distributor of hearing aids based in Italy.[1] Miracle-Ear’s U.S. headquarters are located in Minneapolis, Minnesota.[2] As of 2014 it has more than 1,200 locations in the United States,[2] and it is the best-known hearing aid brand in the U.S.[3] In 2014, the company added several locations in Canada, with plans to open more Canadian outlets.[4] According to the company, Miracle-Ear outlets offer free hearing tests and consultations, and the hearing aids include a risk-free 30-day trial period plus service, warranty, and lifetime after-care.[5][6]

Product history[edit]


"Miracle-Ear" began as a hearing aid manufactured by Dahlberg Electronics, an electronics company founded in 1948. Kenneth Dahlberg started Dahlberg Electronics after he left a position as assistant to the president of Telex Communications, another manufacturer of hearing aids.[7][8] Prior to manufacturing hearing aids, Dahlberg's company produced pillow radios for hospitals and motels.[9][10]

In the early 1950s, Dahlberg Electronics began producing hearing aids that utilized the newly invented transistor technology – beginning with "hybrid" hearing aids that used transistors and vacuum tubes, and then releasing an all-transistor model in 1953.[11] In 1955, they introduced the first so-called "in-the-ear" hearing aid, the D-10 Magic Ear – which concealed all electronic components in a shell snapped onto an earmold, and weighed 1/2 ounce, including battery, three-transistor amplifier, microphone, and receiver.[12][13][14] Other innovations included the D-14 "Solar Ear" eyeglasses hearing aid, which used a solar cell for power.[15]

Further innovations[edit]

In 1962, the Miracle-Ear IV was the first hearing aid that used integrated circuitry,[16] and in 1971, the company introduced the Dahlberg SHARP circuit, an ultra-low power circuit utilizing in-house hybrid production.[17][18] In 1988, the company debuted the Miracle-Ear Dolphin, the first programmable hearing aid on the market.[19][20] In 1997, following university testing, the United States Food and Drug Administration (FDA) approved claims on Miracle-Ear’s Sharp Plus circuitry that the Miracle-Ear devices improved hearing in the presence of background noise.[21][22]

In 1998 the Miracle-Ear Messenger was introduced, which featured proprietary technology that enabled the aid to be customized by the wearer.[23] In 2003 the company's entire line of hearing aids went digital, and in 2005 Miracle-Ear brought out the innovative Open Fit design.[23] In early 2011 the company announced the Miracle-Ear Mirage, an invisible completely in the canal hearing aid that fits deep in the ear canal.[24]

Also in 2011, Miracle-Ear debuted a waterproof hearing aid, called the Aquavi, which is also dustproof and virtually shockproof to accommodate active lifestyles.[25] It can be completely submerged in water up to three feet deep for up to 30 minutes without damage to the instrument,[25] and has an IP rating of 68.[26] In 2013, Miracle-Ear launched a new technology platform called ClearVation, which learns the wearer’s individual preferences and delivers appropriate amplification levels, while preserving natural acoustics. The technology aims to provide a natural hearing experience with a self-customized balance of comfort and clarity, and is available across the Miracle-Ear product line.[27][28]

Additional features[edit]

Miracle-Ear's MEBluConnect and mini MEBluConnect have a Bluetooth radio to receive sound from Bluetooth audio sources, such as cell phones and televisions. Its MEComConnect transmitter also enables electronic devices without Bluetooth capability to transmit Bluetooth audio.[29][30] Miracle-Ear also offers a smartphone application for Android mobile devices, which allows hearing aid adjustments to be made from the smartphone.[31][32]

Current styles[edit]

Miracle-Ear hearing aid styles include behind-the-ear (BTE), receiver-in-canal (RIC), in-the-ear (ITE), in-the-canal (ITC), and completely-in-the-canal (CIC) devices.[33] The Mirage, an invisible CIC (completely-in-the-canal) hearing aid, uses microtechnology and includes feedback cancellation, digital noise reduction, programmable settings, peak smoothing, and SoundBoost volume control.[34][35] Miracle-Ear's Aquavi model is waterproof, dustproof, and virtually shockproof.[25][26]

In 2015, the company announced its new GENIUS technology hearing aids. According to the press release, the technology provides "up to 25% better speech recognition in challenging listening environments than people with normal hearing".[36] The new line of hearing aids offer directional focus, removal of wind noise, zeroing-in on voices and conversations, and high-definition digital sound.[36] They can be fine-tuned to accommodate any specific hearing-loss type, and can be adjusted on the spot to conditions such as wind turbulence and background noise.[37]

Corporate history and activities[edit]

Kenneth Dahlberg sold his company Dahlberg, Inc., and its subsidiary Miracle-Ear, to Motorola in 1959, and subsequently reacquired the company in 1964.[8] Miracle-Ear began franchising in 1984.[3][38] Dahlberg sold the company to Bausch & Lomb in 1993.[39] In 1999 Amplifon acquired Dahlberg, Inc. from Bausch & Lomb, and that year Dahlberg, Inc. and its subsidiary Miracle-Ear, Inc. merged into Miracle-Ear, Inc.[40] In 2014, the company added several locations in Canada, with plans to open more Canadian outlets.[4]

In 1990, the Miracle-Ear Children’s Foundation was founded to provide free hearing aids and services to children for families who could not afford hearing aids.[41] The foundation donated more than 6,500 hearing aids to over 4,100 children in the U.S.[42] In 2013, the Miracle-Ear Children’s Foundation was transformed into the Miracle-Ear Foundation, in order to provide free hearing aids to both adults and children in need.[42][43] In 2014, the Miracle-Ear Foundation initiated and co-sponsored "One Day Without Sound", which encourages hearing persons to remove sound from their lives for one day in order to empathize with hearing loss.[44]

Miracle-Ear was a sponsor of the 1996 Summer Olympics in Atlanta,[45] which included a Miracle-Ear Olympic Hearing Center.[46] A technician at the Miracle-Ear Olympic Hearing Center identified that a member of the Rwandan track team was suffering from severe hearing loss,[47] and Miracle-Ear assisted the runner so that an ear specialist in the U.S. could perform surgeries which restored the athlete's hearing.[45][48][49]
