Abstract: A system includes a candidate device including a processor configured to implement a candidate evaluation software application and a server computer configured to communicate with the candidate device using a network. The server computer is configured to receive, from the candidate device, a request to access an evaluation service. The request includes a candidate identifier. The server computer is configured to access historical candidate data in a memory accessible by the server computer to determine a trust score for a candidate associated with the candidate identifier, and when the trust score exceeds a threshold, transmit a credential to the candidate device enabling an evaluation of the candidate to be performed on the candidate device via a secured local area network.

Abstract: Methods and systems are provided for optimizing call quality and improving network efficiency by reducing bandwidth requirements at the individual-voice-call level. Embodiments provided herein build vocal fingerprints that correspond to the frequency range of the human voice, as well as the frequency range of the voice of individual users. The vocal fingerprints are used minimize and reduce the transmission of background noise and ambient sound captured using HD voice while retaining the frequency range of a user's voice in HD voice. This filtered HD voice frequency range is then transmitted to recipients over the network. The reduced frequency range lowers bandwidth usage and conserves network resources, all while optimizing the call quality for individual users.

Abstract: In one embodiment, an audio system can generate parametrically formulated noise signals. According to an embodiment, an audio system can both determine the hearing ability of an individual and increase the hearing ability of the individual by using parametrically formulated noise. According to an embodiment, an audio system can generate parametrically formulated noise having a power spectrum amplitude that is a function of an individual's hearing threshold across a range of frequencies as measured using parametrically formulated noise test signals.

Abstract: In one embodiment, an audio system can generate a parametrically formulated noise signal which can be adaptively reconfigured according to an input signal. According to an embodiment, an audio system can adaptively adjust a parametrically formulated noise signal according to environmental noise detected by the audio system. According to an embodiment, an audio system can present an adaptive level of activation energy in the presence of environmental noise such that a substantially constant and sufficient level of activation energy can be presented to an individual's auditory system such that additional sound energy corresponding to speech can become audible and intelligible to the individual.
