Determinaram-se o tamanho de parque, densidade de arvores e tamanho do dossel arboreo, e foi medido o nivel de ruido equivalente (LEQ) durante 8-23min por local Enseguida, foi explorada a existencia e significacao de relacoes lineares entre LEQ e tamanho de parque, densidade de arvores e tamanho do dossel.
In theoretical terms, LEQ may be thought of as the constantt sound level over the period of interest that contains as much sound energy as the actual time-varying sound level; in practical terms, LEQ is the usual variable employed in acoustical studies (Wilson, 1989; Canter, 1996; Berglund et al.
For LEQ no such obvious explanation can be found, and it is not clear that the explanation is correct for the highlands.
Hartmann 1979), and since the Incas themselves did not enter the jungle, LEQ cannot be much older than the sixteenth century.
In addition we would have to assume LEQ to be much more conservative than it is.
Finally, we would expect LEQ to be more heavily hispanicized if it had been introduced as a second language of missionaries.
This may well be true, but it certainly does not explain, alone or even together with the missionary theory, the acceptance of LEQ by the Quijos and by numerous other groups as a native language.
Without fluent speakers present, Quechua would never have spread, and LEQ would never have had the extensive highland vocabulary.
Therefore in this study the parameters for each subspecialty that are based on the subset of measurements are considered more accurate and the Figure 3 Leqs by octave band are based on longer measurements.
Examination of Figure 3, shows that Leqs by octave bands for the three subspecialties with the greatest number of noise measurements lasting 70% of the intraoperative phase--orthopaedics, gynaecology, and general surgery, and for neurology--move in concert until the graph for orthopaedic surgery deviates, rising higher than the others at about 2,000 Hz; at 16,000 Hz it has increased by 8-10 dB more than the others.
In the more recent data, a much greater range of Leqs is reported as shown in Table 1.
Interestingly, the overall occupied Leqs in the two wards were not noticeably different (only 2 dB(A) per Figure 2).
