This was done by subtracting the mean intensity in decibels of the utterance from the mean intensity of the constriction period. Doesn't the baths also reject the idea that acoustics should be normative, that there is a prescribed decibel range within which every building should be. The noise level at the test section was approximately 47 decibels, no predominant frequency component was found in the noise. The background acoustic noise is around 47 decibels, and the following measurements were made with a sound intensity about 85 decibels including background noise. The maximum intensity of sound from the loudspeaker was about 100 decibels including the background noise. Decibels were used rather than a straight log-transform due to the common usage of decibels in the perimetry and contrast threshold literature. Weavers were still subject to fatigue from long hours in hot, humid conditions and continuous exposure to high decibels of noise from clattering machinery. It can also be heard on the radio and, at much higher decibel levels, coming from loudspeakers on the back of pick-up trucks. One can define levels of intensities: after the inventor of the telephone we call them decibels (or perhaps phones!). Nearly 75 years old, and suffering from hearing loss (our interview was conducted at a high decibel), he had dedicated much of his life to promoting literacy in his language. The parameter sets were simply arrays of the delay time and amplitude of impulses, with amplitude in decibels relative to one in a sixteen bit dynamic range. These certification requirements place a maximum decibel limit on the noise level that an aircraft may produce. From the Hansard archive Example from the Hansard archive.
