Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

In electrocardiography (ECG) system, a patient cable connecting one or more electrodes to a processing device for processing ECG signals may include one or more electrode connectors mechanically keyed to respective electrodes and/or a device connector mechanically and/or electronically keyed to a cable connector of the processing device.

A heart rate sensor within a hearing assistance device may provide heart rate information or other sensor data, which may be used to determine how well the hearing assistance device fits the patient's ear. The heart rate sensor data provides quantitative feedback that indicates how well the hearing assistance device fits the patient's ear. The heart rate sensor data may be used to provide an indication to the patient to reseat or otherwise adjust the fitting of the hearing assistance device. The improved fitting process provides the ability for the audiologist and patient to identify a preferred or optimized hearing assistance device geometry. This improved fit provides improved performance and reliability of the hearing assistance device.

An electrocardiogram electrode application system includes electrodes that detect electrical signals connected by a single connecting wire and transmitters capable of wirelessly transmitting the detected electrical signals to a computing device for analysis.
