When a person records songs in a recording studio, his or her voice is generally heard through a
headphone along with accompaniment. At this moment, some may argue that if reverb, a sound effect, is
applied, reverberation occurs and this situation could affect vocal accuracy. On the contrary, some argue
that it helps produce positive results by serving as boosting confidence and stability to singers. As sorts of
common sayings, these arguments are circulated and narrated. This study examined these phenomena
through more objective experiment outcomes and accordingly identified reasonable standards for the use of
reverb. According to results from this experiment, the presence of applying reverb of audio monitors in
case of recording songs appeared to have no significant association with vocal accuracy. In addition, results
from a survey conducted among participants and job singers with more than a decade experiences were
consistent with results from this study. For the use of reverb, results showed that as experience increases, it
became irrelevant in the relationship with musical interval and it had tremendously positive effects on
emotion, a significant element in singing, and the upper register vocalization. Thus, this study demonstrated
that adjusting the value of reverb freely according to the taste of recorders and apply it in the process of
recording had more positive aspects.
