“…In one instance, the fork was touching the teeth, and in the other, it was simply held in the mouth. Through this test, Schellhammer discovered that sound conveyed through the teeth was transmitted through the cranial bones, not the Eustachian tube [8][9][10][11].…”

This paper is a summary of the evolution of the tuning fork, a crucial part of the cranial nerves and auditory examination. The tuning fork is a two-pronged fork that resonates at a specific pitch when struck against a surface and has been proven to be incredibly useful in diagnosing and detecting hearing disorders. The tuning fork, an unassuming device in modern medicine, traces its origins back to an era when scientific understanding and medical diagnostics were in their nascent stages. Since its inception, this unpretentious instrument has played a pivotal role in the hands of healthcare practitioners, aiding in the diagnosis and assessment of various medical conditions. This paper embarks on a captivating journey through time to explore the origin, evolution, and significant milestones in the development of the tuning fork. From the first suggestion of differentiating hearing disorders to present-day tuning forks, this paper maps the different stages that the tuning fork has gone through and how its use has changed over time. Along the way, we will discover how the tuning fork has harmonized with music, medicine, and various scientific pursuits, enriching our understanding of sound and resonance while leaving an indelible mark on the course of human history. Delving into the historical context of its creation, this review uncovers the ingenious minds that birthed this innovative device and the pivotal moments that brought it to the forefront of human endeavors.

“…Recently, bone conduction implants (BCI) have been developed that can be applied in people with hearing impairment who cannot use conventional hearing aids [21]- [24]. BCI are attracting increasing attention as a rehabilitation option for patients with hearing loss, and are currently undergoing clinical trials [25], [26]. In addition, BCI have the advantage that implantation requires only minimally invasive surgery with no risk of damaging residual hearing [27], [28].…”

We designed and implemented a two-axis measurement system to inspect the assembly quality condition of a bone conduction implant (BCI) transducer. The system consists of a laser Doppler vibrometer (LDV), XY manual stage, and two digital scale calipers capable of displaying a position coordinate system. To measure the vibration of the cantilever constituting the transducer vibrational membrane, an XY coordinate system was obtained using FEA software. Based on the derived XY coordinate system, the cantilever vibration displacement of the vibrational membrane was measured for each coordinate using the LDV at 0.5, 0.9, and 2 kHz. To visualize the measured area, we developed a Matlab-based application and then visualized the motion of the cantilever. The alignment and misalignment models of the vibrational membrane and permanent magnet were designed using finite element analysis (FEA) software, and the measured cantilever motions of the vibrational membrane were then compared. Finally, to numerically compare the vibration magnitude of the cantilever, the standard deviation was calculated based on the displacement of each edge of the cantilever. The fabricated BCI transducer had a higher standard deviation (3.5 times at 0.5 kHz, 2.3 times at 0.9 kHz) than the ideally aligned FEA model, but the standard deviation was about eight times lower (at 0.5 and 0.9 kHz) than that of the misaligned case. The results of the numerical comparison indicated that the manufactured BCI transducer was very well assembled.

“…Moreover, MEIs are difficult to apply in the absence of ossicles, or when the cochlea cannot be mechanically stimulated because of disease [7,8]. Recently, bone conduction implants (BCIs) have attracted increasing attention for application in people who cannot use conventional hearing aids [9,10]. BCIs are implantable with minimally invasive surgery and do not damage residual hearing [11].…”

This paper describes the finite element design of a vibrational membrane with a cantilever structure to reduce distortion in bone conduction implant (BCI) transducers. To derive the optimal number of cantilevers, a model of ideally aligned components was established based on the structure of a previously proposed transducer, and mechanical vibration analysis was performed using different numbers of cantilevers (two to five). Under the same conditions, similar analyses were performed using vibrational membranes misaligned with the transducer magnet by 0.1 and 0.2 mm. Then, the standard deviations were calculated from the analysis results to numerically compare the magnitudes of vibrations between cantilevers for each cantilever shape. The larger the number of cantilevers, the smaller the standard deviation in both the alignment and misalignment cases. Moreover, from the analysis result, it was confirmed that using a vibrational membrane composed of five cantilevers can reduce distortion in BCI transducers.
