SHUTT: EXPERIMENTS IN JUDGING THE DISTANCE OF SOUND. 7 
centages of underestimation. The figures at the bottom represent 
distances, at which judgments were recorded. 
1. The distance of a sharp noise can be more accurately esti- 
mated than that of a smooth tune. 
2. Judgment is the most accurate with the right side toward 
the sound and most inaccurate with the face toward it. 
3. The tendency is to overestimate the distance of both a sharp 
noise and a smooth tone within thirty-five feet. Beyond that dis- 
tance there is a tendency toward under-estimating. 
4. Within thirty-five feet the tendency to overestimate the dis- 
tance of a smooth tone is greater than it is to overestimate that of 
a sharp noise within the same distance.
