It is not unusual for people to “Google” to satisfy their curiosity or learn about something in a “quick and dirty” way. There is nothing wrong there, provided the reader is aware of the limits of the search engines they are using. Such is the case when trying to decide what are acoustical materials?
Reverberation is one of the essential qualities of an auditorium, concert hall, and any other site intended for listening to speech and/or music and is a starting point for the designer of a room or venue.
The “golden rule” for performing an audiometric test requires the use of a booth; however, there are circumstances where booths are absent.
Measurements and assessment of most noises are relatively easy and have commonly accepted standards There are, however, situations, where most of the energy is concentrated in the lower end of the audible spectra, where the assessment presents problems that are not yet solved.
This is a review of papers accessed from the Google ScholarTM and MendeleyTM databases that deal with risk of hearing loss when mechanical vibrations are also applied to the bodies of noise-exposed workers.
Noise expert Alberto Behar explains why the dB is not a unit at all.
Alberto Behar explores the issue of low-frequency noise.
Other than audiologists and engineers working in industrial noise control, audiologists will almost always use sound level or sound pressure, rather than intensity. When in doubt, use the terms “pressure,” “sound pressure level,” and “SPL” and you will be right 99% of the cases!
Are there harmful effects from the noise generated by the wind turbines and, if the answer is “yes”, what are they and what are the risks they represent?
Alberto Behar wonders why when a noise issue is not hearing hazard, it appears that noise is often not seen as a problem worth considering.
