Abstract: The Present Invention is for a speaker system both standalone and in a phonograph that greatly reduces sympathetic vibration and feedback due to interaction of sound vibration transmitted from bass speakers to the chassis. The solution is twofold. First, the speakers are mounted in a substantially airtight enclosure. Second, the substantially airtight enclosure is suspended within the sound system chassis using elastic members in tension. A typical elastic member is an extension spring. In a phonograph, the elastic suspension almost completely isolates vibrations of the speaker enclosure from the phonograph chassis, thereby drastically reducing sympathetic vibration and feedback, and accommodating new depths of bass extension.

Abstract: Disclosed herein are systems and methods enabling self-fitting by a non-expert consumer. The method in some examples involves transmitting a wireless command by a computing device to a hearing device in-situ to produce a sequence of test audio signals corresponding to natural sound segments, while allowing the consumer to adjust fitting parameters based on perceptual assessment of hearing device output. The sound segments may represent a practical range of sounds within the normal human auditory range, with each sound segment selected to correspond to one or more fitting parameters of the programmable hearing device. The consumer is instructed to listen to the output of the in-situ hearing device and adjust controls on the personal computer's graphical user interface related to corresponding fitting parameters. The systems and methods disclosed herein allow dispensing or adjusting of hearing devices without requiring specialized instruments or clinical settings.
