A system for validation of a hearing aid performance, especially in small children is disclosed. The validation of the performance of hearing aids after having being fitted to a small child who is not able to subjectively provide responses to sounds presented to the child via the hearing aids, is instead done in an objective manner, by using a naturally occurring signal, which has been modulated in order to create an ASSR evoking speech stimulus which is not considered as noise by a hearing aid.

Provided are methods comprising presenting a sensory environment to an individual experiencing the effects of a psychoactive agent, monitoring the neural status, the physiological status, or both, of the individual, and presenting a modified sensory environment to the individual based on the monitoring. In certain embodiments, the agent is a psychedelic agent. According to some embodiments, presenting a sensory environment to the individual comprises presenting to the individual a visual stimulus, an auditory stimulus, a tactile stimulus, an olfactory stimulus, or any combination thereof. In certain embodiments, presenting a modified sensory environment to the individual comprises presenting a customized sensory environment to the individual in real-time based on the monitoring. In some embodiments, the individual is suffering from a mental health condition selected from depression, anxiety, post-traumatic stress disorder (PTSD), addiction, and any combination thereof. Systems that find use in practicing the methods of the present disclosure are also provided.

A method and device allowing a physiological signal, typically representative of brain activity, to be transcribed in the form of sensory signals perceptible to a human user, typically acoustic signals is provided. For this purpose, a physiological signal is acquired and then analysed in such a way as to detect therein patterns that are then parameterised in the time domain. One or more parameters of these patterns are used to determine one or more parameters of the generated sensory signals and/or to determine one or more parameters of temporal envelopes used to modulate the sensory signals. This method and device can be applied, in particular, to neuro-acoustic transduction.

A method and an apparatus for enabling adaptive audio signal alteration are described. When an input audio signal is received, a determination of whether the user of an audio device hears the input audio signal is performed based upon brain activity of the user. A determination of whether the user is distracted by the audio signal is performed based upon sensor measurements indicating a physical state of the user. In response to determining that the user hears the input audio signal and that the input audio signal causes the user to be distracted, a determination of configuration parameter(s) is performed. An alteration of audio signal(s) is caused based upon the configuration parameter(s) to obtain modified version(s) of the audio signal(s) that are intended to address the distraction caused by the input audio signal, and output audio signals are output, where the output audio signals include the modified versions.
