Biological Effects of High Frequency Sound

“…results suggest the existence of a previously unrecognized response to complex sound containing particular types of high frequencies above the audible range. We term this phenomenon the ‘hypersonic effect.” May explain why most listeners can hear a supposedly impossibly high-frequency difference between a 12 kilo Hertz square wave versus a 12 kilo Hertz sine wave. … Read more

Functional anatomy of musical processing in listeners with absolute pitch and relative pitch

The functional anatomy of musical processing in listeners with absolute pitch (AP) and relative pitch (RP) has been a topic of interest in neuroscience research. Absolute pitch refers to the ability to identify or produce musical pitches without the need for a reference tone, while relative pitch refers to the ability to perceive and understand … Read more

Musicians have enhanced subcortical auditory and audiovisual processing of speech and music

Indeed, research has shown that musicians often exhibit enhanced subcortical auditory and audiovisual processing compared to non-musicians, particularly when it comes to speech and music stimuli. The subcortical auditory system includes structures such as the brainstem and thalamus, which are involved in the early processing of auditory information before it reaches higher cortical regions. Several … Read more

Musical rhythm spectra from Bach to Joplin obey a 1/f power law

Much of our enjoyment of music comes from its balance of predictability and surprise. Musical pitch fluctuations follow a 1/f power law that precisely achieves this balance. Musical rhythms, especially those of Western classical music, are considered highly regular and predictable, and this predictability has been hypothesized to underlie rhythm’s contribution to our enjoyment of … Read more

Listening to tailor-made notched music reduces tinnitus loudness and tinnitus-related auditory cortex activity

Abstract   Maladaptive auditory cortex reorganization may contribute to the generation and maintenance of tinnitus. Because cortical organization can be modified by behavioral training, we attempted to reduce tinnitus loudness by exposing chronic tinnitus patients to self-chosen, enjoyable music, which was modified (“notched”) to contain no energy in the frequency range surrounding the individual tinnitus … Read more

Fear across the senses: brain responses to music, vocalizations and facial expressions

Abstract   “…subject-specific amygdala responses to fearful music and vocalizations were correlated, consistent with the proposal that the brain circuitry involved in the processing of musical emotions might be shared with the one that have evolved for vocalizations. Overall, our results show that processing of fear expressed through music, engages some of the same brain … Read more

Psychophysiological reactions to music in male coronary patients and healthy controls

Abstract   “The study supports the following conclusions: (1) music-listening produces significant decreases in the blood pressure (both systolic and diastolic) and heart rate of coronary patients but has no significant effect in healthy controls; (2) music-listening reduces stress, anxiety, and depression, enhances life satisfaction, optimism and hope, and makes life more meaningful in both … Read more

Soul Resonance and Music, montalk.net

“Soul Resonance and Music” is a concept discussed on montalk.net, a website that explores various topics related to metaphysics, consciousness, and spirituality. While I cannot access specific content from the website, I can offer insights into the general idea of soul resonance and its connection to music based on common themes in metaphysical literature: 1. … Read more

Tubes vs Transformers – What good tube “tone” looks like

Metal and wire is just metal and wire. The real sonic magic comes from the tubes. GAGA gets all that metal out of their way. An examination into the esoterica shrouding audio output transformers, tubes and “tone”, or the various unpleasant effects of bulky metal on faithful, musical amplification. Whereas traditional output transformers – homogenizing … Read more
