A new hearing profile assessment plays each of a plurality of frequency tones multiple times at a plurality of loudness levels. For each frequency, the patient indicates which tones that they can hear, establishing minimum-amplitude thresholds for each frequency. The assessment adapts loudness levels until the patient indicates consistent minimum-amplitude thresholds for each frequency. Also, a new system for training the hearing of a subject is disclosed. The system instructs the subject to vocalize various sound items and remember the sounds that they vocalize. The system plays either recorded samples of the subject's own voice, or comparison samples of a synthesized voice or other's vocalizations of the same sound items. The system prompts the subject to compare the played samples with the sounds they remembered vocalizing. The system uses the feedback to adjust sound processing parameters for a hearing aid, cochlear implant, sound output devices, or a training program.

The present invention provides a bionic sleep biological rhythm alarm clock. The bionic sleep biological rhythm alarm clock employs light simulation with special frequency to induce people in sleep tobe always weaken up in a light sleep period according to a brain electrical rhythm synchronization effect, and finally, an effect of simulation of natural wakeup is achieved. A deep sleep period takes Delta waves as main waves, and the light sleep period takes Theta waves as main waves. When light simulation with a frequency range of 3-8Hz is acted on a brain, brain wave frequencies can be changed from an original frequency range to a simulation frequency range. Therefore, people in sleep are induced by employing the light simulation with special frequency to allow the people who are waken upto be still in the light sleep period so as to eliminate people's fatigue feeling such as dizzy and sleepy and the like. According to the brain electrical rhythm synchronization effect, the bionic sleep biological rhythm alarm clock can simulate a nature awakening state through light induction, can induce the people in sleep to be waken up in the light sleep period to allow the people to be fullof energy when the people are waken up without any fatigue feeling.
