From the article: "A recent independent review evaluated twelve common acoustic stethoscopes on the basis of loudness, clarity, and ergonomics. They did acoustic laboratory testing and recorded heart sounds on volunteers. The results are listed by brand and model. [7] Eli Finkelstein (2008-07-01). "The Ultimate Acoustic Stethoscope Review".
A 3D-printed stethoscope is an open-source medical device meant for auscultation and manufactured via means of 3D printing. [31] The 3D stethoscope was developed by Dr. Tarek Loubani and a team of medical and technology specialists. The 3D-stethoscope was developed as part of the Glia project, and its design is open source from the outset.
The amplifier (an electronic circuit) increases the amplitude of the electric signal using a power source (battery). The speaker converts the amplified electric signal back into a sound wave. The volume (gain) control is used to adjust the amount of amplification applied to the electric signal and thus, indirectly, controls the sound volume.
TV Ears were designed with their target audience of the hearing impaired and senior citizens in mind. Unlike regular headphones, TV Ears use an under the chin design, similar to that of a stethoscope, [3] [9] with the right and left ear tips connected by the receiver in the center, which then goes under the chin.
