Innovation Reveals the Impact of Boosting Hearing via Blood Conduction

A new study conducted by NeuroAudit from Israel has found side effects and unveiled a revolutionary hearing technology capable of boosting human hearing via blood conduction.

This innovation marks a significant advancement in hearing technology, offering a promising future solution for individuals with hearing loss.

Hearing amplification expanded up to 100 kHz

NeuroAudit’s technology can boost hearing up to 100 kHz (5 times the normal human hearing) without using the auditory system.??

Unlike traditional hearing aids, which often fall short of restoring hearing to pre-loss levels, NeuroAudit’s technology employs advanced brain stimulation with ultrasound to amplify sound vibrations directly through blood vessels to the auditory brain. The technology targets specific modulation frequencies and directly stimulates the brain’s auditory pathways by blood conduction.

This unique method bypasses the conventional air conduction pathway, providing a more direct means of hearing enhancement.

According to the founders, an innovative technology called “Brain Hearing Sense “can expand the range of human brain hearing by up to 5 times the normal limit, reaching up to 100kHz without using the auditory system. This breakthrough approach opens up a new dimension in human sensory experience to improve quality of life and well-being.

Addressing Conductive and Mixed Hearing Loss

According to the founders, the technology could benefit individuals with conductive hearing loss, a condition caused by damage of the outer or middle ear. Traditional hearing aids are often ineffective for these cases, but by bypassing the damaged areas, NeuroAudit’s technology presents a new pathway for hearing functionality by blood vessels.

The technology shows promise for those with mixed hearing loss—a combination of conductive and sensorineural hearing loss by addressing the conductive component and enhancing hearing.

Background

Ultrasound (US) has gained significant attention as a promising technology for targeted, non-invasive neuromodulation due to its capacity to induce electro-physiological and motor responses.

One theory suggests that ultrasonic signals resonate within the brain and are then modulated to frequencies that the cochlea can detect.

The Japanese researcher Tsutomu Oohashi introduced the term "hypersonic effect" to describe the findings of a controversial study that supported the potential audibility of ultrasound. Oohashi conducted objective and subjective experiments in which subjects listened to music, some containing high-frequency components (HFCs) above 25 kHz and some without. Oohashi claims that even though humans cannot consciously hear ultrasound, the presence or absence of these frequencies has a measurable impact on their physiological and psychological reactions.

Notably, the hypersonic effect did not occur when the HFCs were transmitted via headphones. Additionally, a 2006 study investigated the comfortable listening level (CLL) of music with and without HFCs as an alternative method of measuring subjects' responses to the sound.

However, there are contradictions in Oohashi's results. Oohashi's study found no effect on listeners when only the ultrasonic portion of the test material (frequencies higher than 24 kHz) was played. The observed effect was only present when comparing full bandwidth to bandwidth-limited material. Researchers from the NHK laboratory have been unsuccessful in reproducing Oohashi's results, and studies cited as contrary evidence did not address the physiological brain response to high-frequency audio, but rather the subjects' conscious response to it.

NeuroAudit researchers state that to better understand the clinical aspect, it is essential to comprehend that the auditory cortex is part of the temporal lobe and processes auditory information in humans and other vertebrates. It is situated bilaterally, roughly at the upper sides of the temporal lobes. The auditory cortex participates in the spectrotemporal analysis of input from the ear, which involves time and frequency. Additionally, it filters and transmits information to the dual-stream model of speech processing. The auditory cortex is the brain's most highly organized processing unit of sound.

Psychoacoustics Neuromodulation Technology Practice

Neurons in the auditory cortex are arranged according to the frequency of the sound to which they respond most effectively. The primary auditory cortex can be modulated by various neurotransmitters and exhibits distinct responses to sounds in the gamma band. It has been postulated that gamma frequencies are resonant frequencies of certain brain areas.

Sounds entering the auditory cortex are processed differently based on whether they are perceived as speech. According to the strong and weak speech mode hypotheses, when people listen to speech, they respectively engage unique perceptual mechanisms specific to speech or utilize their knowledge of the language as a whole.

NeuroAudit researchers believe that this ability constitutes an innovative Psychoacoustics Neuromodulation technology for treating targeted brain disorders.

Improving Quality of Life and Well-being

Beyond its technical capabilities, this breakthrough has profound implications for overall well-being. Research shows that hearing loss can lead to social isolation, depression, and cognitive decline. By boosting hearing levels, the technology could lead to maintaining mental health and more fulfilling lives.

Looking ahead, NeuroAudit seeks to integrate this innovative technology into various devices, including smartphones, hearing aids, and headphones, making it a discreet and convenient option for users. This adaptability underscores the technology’s potential to become a standard tool in hearing enhancement.

Potential for Widespread Application

NeuroAudit commits to making this revolutionary technology accessible for many people and is inviting healthcare providers and researchers to collaborate on the development and commercialization of this technology. The goal is to work together to accelerate the adoption of blood-conduction hearing enhancement and to significantly improve the lives of individuals with hearing loss and cognitive decline.
