The present paper aims to address the problems of the urban environment as an area of interaction between urban forms and urban noise. This interaction is intended to be monitored using urban indicators, by comparing the effects of noise propagation using models of urban forms. The model of noise prediction allowed developing noise studies in facades, resulting in noise levels in a calculation grid located in the building facades. The study will allow the creation of different scenarios and anticipate as early as in the preliminary building design phase, which facades would be exposed to higher noise levels. The effects of noise in facades can then be minimized in advance, by adjusting the layout of the urban typology.

RESUMO1 Recebido para publicação em 15/10/97 e na forma revisada em 24/08/98. 2 Parte da tese do primeiro autor apresentada à UFV para obtenção do título de Doutor em Agronomia. 3 ABSTRACT Chemical weed control in sucessive crops of corn and field beanThis trial was carried out at the Sooretama Experimental Farm, in Linhares, State of Espírito Santo, Brazil, in order to evaluate the efficiency of herbicides on weed control in sucessive crops of corn and beans. The comercial mixture of atrazine plus metolachlor was more efficient to control weeds in corn (Zea mays) crop than atrazine and metolachlor applied alone. The comercial rate of 8,04 l ha ).
