Non-double-blind studies with subjective sound judgments are often not accurate. The order of rated sounds matters in simple "blind tests". Something a proper double-blind study is not affected by.

Aphantasia is the inability to evoke one's own imagined conscious images. "Anauralia" is the inability to evoke one's imagined conscious sounds. https://nautil.us/people-who-cant-picture-sound-in-their-minds-517529/?_sp=d08e4762-57b3-4197-8a41-d7d361f9fc05.1710337141622 How does the audiophile...

When listening to mono music on a Yamaha NS1000, a height of 0.65 m next to an Apogee Duetta, a height of 1.5 m, the sound from the Yamaha speaker was perceived as clearly smaller despite the possibility of reproducing higher sound pressure, and more bass with lower distortion. Another box...

"Psychoacoustic researchers" usually have a technical background. In the physical dimension, only a few measurements are required to obtain sufficient validity and reliability. When they conclude how measurements in physics affect hearing they make a big mistake. Now "psychoacoustics...

My knowledge in this area is limited but I still want to try to understand. The signal pattern in neurons - trains of action potentials - is similar to the Fourier transform. Common sine signal action potentials are not that difficult to understand in relation to the Fourier transform. But what...

A team of researchers from the Heidelberg Institute for Theoretical Studies (HITS) and Oxford University has found that some black holes produce distinctive sounds when they merge, regardless of their origin. https://www.techexplorist.com/universal-sound-black-holes/65815/

Newly broken stereocilia on the hair cells in the inner ear are repaired within a week via a newly discovered process. Possibly, this new process could open up the repair of older injuries. I suspect there are many potential patients/customers here on this forum. The market for a pill with this...

Bone-conducted ultrasounds (BCU) are sensed physiologically differently from normal air-conducted hearing. Bone-conducted ultrasounds do not produce a tonotopic stimulation of neurons in the brain. That is, the nerve cells are not stimulated from low to high frequencies. Other regions appear to...

It is important to understand that Psychoacoustics and Audiology are only related sciences to the only science of hearing - Neurophysiology. Physics/acoustic is the only science that describes physical stimuli on the eardrum. Audiology is the only science that describes the sensory response to...

Rank the most important variables to obtain optimal sound perception in the listening position. Rank from the most important to the least important. Please justify the ranking position if possible. Describe how the variables are interrelated.

Most people have an inner voice that is audible. In dreams, sounds are experienced. Earworms can be bothersome. Healthy people can hear internal sounds without external stimuli or experiencing hallucinations. This is not unusual. But most people do not want to admit this as they are afraid of...

Describe your decisive experience that completely changed your view of audiophilia with a comment. A classmate had found a pair of used German (Siemens?, Klangfilm?) studio monitors. I was completely surprised that out of our old records came a completely new sound dimension with...

There is a lot written about the importance of "good" sound dispersion in speakers! What is "good" dispersion without relation to the room? How is the room related to "good" spread? Are there studies on this topic published in major journals by anyone other than Toole and Olive?

To my knowledge, Harman's Spinorama related double-blind studies have not been reproduced and confirmed by other independent researchers in other listening rooms. Can the findings be extrapolated to rooms other than Harman's specific listening room? What are the acoustic properties of the room...

In the brain, the speech and the song share some areas but not all. Mandarin, for example, is a tonal language, while most languages are atonal. Several animal species communicate with non-verbal signs, but some use sounds and even tonal songs. Mating songs are common.

The perceived sound of the dipole speaker is, as I see it, essentially different from the box speaker. Exactly what physical facts are related to these perceived differences and exactly how are these physical facts related to best subjective experience? What are the advantages and...
