In general, the verification to prediction formula in a national road and the main street of atown has been used recklessly in Korea. Therefore we investigated the validity of an existingprediction formula (NIER(87, 99), TR-Noise, KLC(2002)) with correction relationship which wasbased on both the prediction formular from apartment complex in the field and height 1.5mfrom the surface level. On the results of measuring the noise level form an isolated distance, thenoise level showed that it was 4.5∼5.5dB(A) by reason of becoming 2 folder far from a source.From the distribution of noise level measured by the apartment floors, the measurement point(1st floor) was 58.7~71.4dB(A) at its lowest level and the middle floors (3, 5, 7 and 10) were thehighest distribution of noise level. From the analysis results on the application validity to anexisting prediction formular (NIER(87, 99), TR-Noise, KLC(2002)) in the height 1.5m, thecorrection coefficients were 0.95∼0.96 and the measured values were reasonably close to thepredicted values, indicating the validity and adequacy of the predicted models. KLC(2002)model was found accurate within 3dB(A) with 36 data out of the total 42 data, showing themost accuracy among the predict models. However, the developed models have to improve theaccuracy with a various of factors
