Özet
Purpose of this study is to generate Sound Quality Index (SQI) in order to estimate pleasantness of users with sound environment in urban spaces by employing
sound quality metrics together such as loudness, sharpness and roughness, which
are frequently stated in soundscape studies as it is directly related to human perception. For this purpose, binaural sound records have been conducted and quantitative data of loudness, sharpness and roughness of these metrics of the sound
records has been calculated. 27 sound clips, containing diferent quantitative data
of each of the three metrics, have been generated by picking them out of binaural
sound records. Participants have listened to the sound clips at laboratory environment, and have been applied jury test. Correlations between pleasantness of
users with sound environment and sound quality metrics have been determined
by analyzing results from jury test and quantitative data of sound clips. SQI has
been generated with a correlation model by using Regression Analysis method. In
order to check the accuracy of the model, surveys have been conducted on users
at the feld and binaural sound records have been taken simultaneously to the
surveys. Quantitative data obtained from sound records has been calculated by
SQI, and pleasantness level of users with sound environment has been estimated.
Results obtained from surveys conducted at the feld and results estimated by SQI
have been compared. Apart from quantitative data of sound records, efect of parameters that might afect pleasantness of users with sound environment in urban
spaces has been determined.
