Background: Over the past two decades, the increasing and unregulated production of infra-sound and low frequency noise (ILFN, ≤200 Hz) has led to a considerable rise in associated noise complaints and health-related issues. The most recent of such ILFN sources are industrial wind turbines (IWT). Acoustical field-data was collected within a home lo...

Within the context of noise-induced health effects, the impact of airborne acoustical phenomena on biological tissues, particularly within the lower frequency ranges, is very poorly understood. Although the human body is a viscoelastic-composite material, it is generally modeled as Hooke elastic. This implies that acoustical coupling is considered...

The acoustical spectrum is usually divided into two major segments: that which can be heard by the human ear, and that which cannot. Moreover, it is usually maintained that if acoustical phenomena do not hurt the ear, then they will have no other bodily effects. In the electromagnetic (E&M) spectrum, there is also a segment capable of being perceiv...

Noise exposure is known to cause hearing loss and a variety of disturbances, such as annoyance, hypertension and loss of sleep. It is generally accepted that these situations are caused by the acoustical events processed by the auditory system. However, there are acoustical events that are not necessarily processed by the auditory system, but that...
