Pulse, San Diego, a Technitrol Company, which specializes in electronic component and subassembly design and manufacturing, is showcasing its latest developments in microphones, receivers, telecoils, and electromechanical components for hearing instruments at the International Congress of Hearing Aid Acousticians (EUHA) in Germany.

The DCU Scroller is a high-quality component that provides a simple and discreet method for adjusting hearing aid volume. Wearers can change the volume of the digital control unit almost unnoticed using a linear scroll. Its body diameter of 3.8mm (0.15 inches) makes it small enough to be used for both behind-the-ear (BTE) and in-the-ear (ITE) hearing instruments.

The 4000 series receivers measure 26.5mm3 (0.297 inches by 0.106 inches by 0.077 inches). The series excels in low vibration that enables higher gain and output levels in many receiver-in-the-canal (RIC) and completely in-the-canal (CIC) systems.

The push-button PB 100 Click, at a diameter of 1.9mm (0.075 inches), is a small tactile switch for hearing instruments. It has an added detent function that makes the hearing aid user feel a discreet click when the bottom is pressed, which is accomplished without compromising the click’s quality. The device is intended for ITE and BTE instruments where space is at a premium. 

The 8800 Microphone Series now features an improved power-supply rejection ratio along with better ultrasound suppression, improved sensitivity, and less noise compared to a standard microphone. 

Visitors to the booth can see, hear, feel, and receive information about the C-Barrier, the company’s total wax and moist protection system, which can be easily cleaned and replaced, and increases the life expectancy of hearing instruments. It comes in tape-and-reel packaging for optimized production processes at hearing instrument manufacturers and in an easy-to-use dispensing box of four sets for the end user.
