However, it's been argued that despite waves the microwave auditory effect only constituting a rapid 10 −6 °C rise in temperature, for threshold peaks on each pulse, that, at the least, a strong peak of around 1400 kW/cm² (1.4 billion mW/cm²) would certainly be harmful due to the resulting pressure wave.
Composers have long been using the spatial components of music to alter the overall sound experienced by the listener. [14] One of the more common methods of sound synthesis is the use of combination tones. Combination tones are illusions that are not physically present as sound waves, but rather, they are created by one's own neuromechanics. [15]
Hearing is not a purely mechanical phenomenon of wave propagation, but is also a sensory and perceptual event. When a person hears something, that something arrives at the ear as a mechanical sound wave traveling through the air, but within the ear it is transformed into neural action potentials. These nerve pulses then travel to the brain ...
Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exterior ear, and enter the ear canal. In mammals, the sound waves vibrate the tympanic membrane , causing the three bones of the middle ear to vibrate, which then sends the energy through the oval window and into ...
The internalization process of the inner voice is the process of creating an inner voice during early childhood and can be separated into four distinct levels. [14] [65] [67] Level one (external dialogue) involves the capacity to maintain an external dialogue with another person, i.e. a toddler talking with their parent(s).
The Outer ear consists of the pinna or auricle (visible parts including ear lobes and concha), and the auditory meatus (the passageway for sound). The fundamental function of this part of the ear is to gather sound energy and deliver it to the eardrum. Resonances of the external ear selectively boost sound pressure with frequency in the range 2 ...
However, if we define sound as the waves themselves, then sound would be produced. This all leaves out sounds heard from imagination, hallucination, synesthesia, and tinnitus. These phenomena prove that sound is virtualized reality since these all exist without vibration in the air. The same applies to all other senses that produce perceptions.
The stapes transmits sound waves to the inner ear through the oval window, a flexible membrane separating the air-filled middle ear from the fluid-filled inner ear. The round window, another flexible membrane, allows for the smooth displacement of the inner ear fluid caused by the entering sound waves.
