“…The TU-1000 skull simulator simulates properties of the average mastoid bone and overlying tissues (IEC, 1990). The Divino connects to the TU-1000 skull simulator via an abutment similar to the titanium abutment implanted in the mastoid (see Håkansson and Carlsson, 1989;Stenfelt and Hå kansson, 1998 for a more detailed description).…”

Background-Patients with unilateral sensorineural hearing loss (USNHL) experience great difficulty listening to speech in noisy environments. A directional microphone (DM) could potentially improve speech recognition in this difficult listening environment. It is well known that DMs in behind-the-ear (BTE) and custom hearing aids can provide a greater signal-to-noise ratio (SNR) in comparison to an omnidirectional microphone (OM) to improve speech recognition in noise for persons with hearing impairment. Studies examining the DM in bone anchored auditory osseointegrated implants (Baha), however, have been mixed, with little to no benefit reported for the DM compared to an OM.

“…The TU-1000 skull simulator simulates properties of the average mastoid bone and overlying tissues (International Electrotechnical Commission [IEC], 1990). The TU-1000 skull simulator connects to an Audioscan Verifit (which measures output force level in dB SPL), and the Ponto Pro connects to the TU-1000 skull simulator via an abutment similar to the titanium abutment implanted in the mastoid (see Carlsson, 1989, andStenfelt andHå kansson, 1998, for more detailed descriptions).…”

Background: Current bone anchored hearing solutions (BAHSs) have incorporated automatic adaptive multichannel directional microphones (DMs). Previous fixed single-channel hypercardioid DMs in BAHSs have provided benefit in a diffuse listening environment, but little data are available on the performance of adaptive multichannel DMs in BAHSs for persons with unilateral sensorineural hearing loss (USNHL).

“…Compared to the standard abutment, the BI300 abutment is a concave-shaped abutment. The direct coupling for the mechanical vibrations to the skull provides effective sound transmission of around 5-15 dB higher than the transcutaneous coupling of conventional BC devices [7]. Because the Baha sound processor is coupled directly to the skull without interference from intermediate tissue, some drawbacks of conventional transcutaneous BC devices are avoided.…”

In the past 30 years, a large amount of clinical and audiological research on bone conduction hearing devices has been performed. In this review, we give a brief history of the developments in indications, surgical techniques and sound processors with respect to implantable bone conduction devices like the bone-anchored hearing aid or Baha. Starting with the use of Baha in patients with bilateral conductive or mixed hearing loss (HL), the indications for such devices have been extended to patients with unilateral HL, children and moderate mentally retarded patients. Bilateral fitting has been shown to be beneficial in restoring binaural hearing in patients with bilateral acquired or congenital conductive HL. In addition, the surgical techniques used to implant the titanium fixture for Baha application have been modified and further developed to reach two main goals: (a) optimal osseointegration, and (b) preparation of the implant site to minimize the occurrence of soft tissue reactions. Currently, the most used techniques are the pedicled skin flap, dermatome and linear incision techniques. Several generations of the Baha(®) sound processor have been developed by Cochlear(TM) to provide sufficient amplification in different hearing situations. Improvements in sound quality, aesthetics and handling have been major points of interest. The Baha sound processors most often used today are the Baha(®) Divino, the Baha(®) Intenso and the Baha(®) Cordelle. Recently, the more flexible Baha(®) BP100 sound processor was launched.
