Individuals with exploding head syndrome hear or experience loud imagined noises as they are falling asleep or are waking up, have a strong, often frightened emotional reaction to the sound, and do not report significant pain; around 10% of people also experience visual disturbances like perceiving visual static, lightning, or flashes of light.
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.

In these, people more often hear snippets of songs that they know, or the music they hear may be original. They may occur in mentally sound people and with no known cause. [5] Other types of auditory hallucinations include exploding head syndrome and musical ear syndrome. In the latter, people will hear music playing in their mind, usually ...
Tinnitus is the presence of noises in the ear without an external stimulus. Tinnitus sounds different for everyone. Some of my patients describe it as ringing, buzzing, humming, chirping ...
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 ...
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]
Two days into her treatment, she started to experience musical hallucinations, which consisted of four musical pieces. The music persisted until three days after cessation of the drug. Although the patient was taking other medications at the same time, the timing of onset and offset suggested that amantadine either had a synergistic effect with ...
Sound levels as low as 40 dB(A) can generate noise complaints [43] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower. [ 44 ] Other factors that affect the annoyance level of sound include beliefs about noise prevention and the importance of the noise source, and annoyance at the cause (i.e., non-noise related ...
