Can anyone help me with resources to understand human hearing. I want to know more about how human ear works, how humans hear, what they hear but cannot remember hearing.

 

I hope you're not unrealistically expecting to find a quickie solution.
Two books below are fabulous reference books.
They are both well balanced i.e.,
- they're not trivial
- they are thorough but not as insanely technically deep as some other serious reference books.

The two books complement each other nicely.
As the chapter titles indicate...
- the first book is focussed more on acoustics and hearing
- the second book is focussed more on hearing music specifically

[1] Hearing - An introduction to psychological and physiological acoustics - 5th Ed (2009) - Stanley Gefland
Chapters: Physical Concepts; Anatomy; Conductive Mechanism; Cochlear Mechanisms and Processes; Auditory Nerve; Auditory Pathways; Psychoacoustic Methods; Theory of Signal Detection; Auditory Sensitivity; Masking; Loudness; Pitch; Binaural and Spatial Hearing; Speech and Its Perception.

[2] How We Hear Music - The Relationship between Music and the Hearing Mechanism (2003) - James Beament
Chapters: Preliminaries; Aural archaeology; Hearing selects intervals; The beguiling harmonic theory; The imitating voice; Hearing simultaneous pitches; Patterns in harmony; Loudness; Music through the hearing machine; A sense of direction; Time and rhythm;

Where? Try Libgen.

Good Luck!

How Hearing Works

 

A large and complicated topic!

A good approach is to separate it into the physical aspects and the cognitive aspects. Of course, the two can't really be separated!

Brian Moore's An Introduction to the Psychology of Hearing is a good place to start.

 

Master Handbook of Acoustics by F. Alton Everest & Ken C.Pohlmann has a very good section about human hearing. It's a book everyone interested in sound engineering should own

 

Thank you all for these suggestions.

Can anyone tell what happens to the tympanic membrane when ultrasound interacts with it? Will tympanic membrane vibrate or not, if it vibrates will it send the signal to cochlear?

It doesn't anything about what happens to tympanic membrane when ultrasound interacts with it. Will tympanic membrane vibrate or not, if it vibrates will it send the signal to cochlear?

 

Researcher examines risks of infra and ultrasound
Noise can cause hearing loss. Are there any triggers that cannot be heard or felt? Read more about it here.

Most people cannot hear either infra or ultrasound . Previously it was assumed that these inaudible sound waves were harmless. The scientist Timothy Leighton from the University of Southampton in England doubts it.

Noise is caused by vibrations and spreads out as sound waves. The strength of the sound - the sound pressure - can be measured. The displayed measured value is the sound pressure level, which is given in decibels. If there are pressure fluctuations, these are perceived by the human ear. The number of oscillations per second - the frequency - determines the "pitch". The higher a frequency, the higher the tone. People hear tones that are in the frequency range between 16 and 19,000 Hertz. They can best perceive tones between 2,000 and 5,000 Hertz. Among other things, conversations take place within these pitches.

Children with healthy hearing can even hear up to 30,000 hertz when they are born. However, the ability decreases over the lifespan, because the cilia in the ear are destroyed by the noise exposure in everyday life. And it is precisely these that are responsible for the transmission of the sound waves in signals that are recognized as noise in the brain.

Ultrasonic tones are at a frequency of over 19,000 hertz, while infrasound tones are below the value of 16 hertz. Most people do not hear infrared or ultrasound because the tones are too low or too high. Few adults are able to hear frequencies of 20,000 hertz. The tones are then only perceptible as a beeping sound.


Few people notice ultrasound
Modern everyday life no longer works without ultrasound. Countless devices use these waves as signals. At train stations, loudspeakers constantly send ultrasonic waves, while ultrasonic sensors are responsible for the automatic opening of doors. Some people seem to be able to hear and feel ultrasound as well. They often react with dizziness, nausea, tinnitus or headache.

Professor Leighton has been researching ultrasound waves for several decades and is one of the most important experts in the field. In his most recent publication, he warns that the ultrasound transmitted through the air can be harmful to health. To prove his thesis, he started measuring ultrasonic waves in public places. With his team, he has investigated whether ultrasonic waves occur at train stations, in schools, sports stadiums, swimming pools, museums, libraries and inside cars and how high their intensity is.

The existence of ultrasonic waves could be proven at each of these locations. The strongest waves came from public address systems. Some volunteers on Leighton's team complained of headaches and dizziness near these devices. After this measurement success, the expert studied ultrasound guidelines that existed around the world, all of which date from the 1960s and 1970s, but have never been revised.


Low limits
Leighton assumes that the previous limit values were classified too low and that the waves can definitely affect the health of sensitive people. However, many doctors doubt this. Since the inaudible tones do not touch any cilia, they cannot be destroyed by the sound. The Swiss ear, nose and throat doctor Andreas Schapowal is also critical of Leighton's thesis, but calls for a more precise definition of ultrasound. Devices that work with ultrasound should use frequencies that are significantly higher than 20 kilohertz. So they cannot be heard by adults and children.

If you're now drifting into discussing Infrasonics and maybe you should be worried about bowel movements

My thinking is that since tympanic membrane will vibrate to any pressure in airwaves, this movement will be passed onto cochlear, but I can't guess what happens from there.
