Details are shown below.
Case 1
Improvement
The amplification of the sound should be adjustable, as the vehicle is driving or is stopped.
The point at issue
The interactive soundscape system decreases the volume when the car comes to a halt. However, the loudness that attributes of auditory sensation is not changed by the pitch. The human auditory system has different sensitivity to hight of frequencies. The sensation of hearing is sensitive to high-pitched tone and insensitive to bass. The road noise that the wheels receive while driving is low frequency. Therefore, when the car stops and the noise goes, the sounds are felt greater than general occasionally. The interactive soundscape contains several high pitches. For example, bird voice, wind chimes and so on. Besides that, the setting of the volume which varies with distance was not effective. The problem is that the reduction of the sound was not proportional to the distance from the landmark when the automobile held.
Solution
The problem is improved when psychological characteristics are incorporated into the volume setting.
The decreasing of the volume must also depend on the distance when the car is not …show more content…
The point at issue
The acoustic system inserted into the vehicle was insufficient, consequently, the detailed sound could not be presented.
Solution
In order to display the details of the quality, a powerful audio system is required.
Case 4
Improvement
It is desirable that the position of the target landmark is able to be distinguished.
The point at issue
In this system, the location of the building is unable to be confirmed. Consequently, passengers do not find which direction to see occasionally.
Solution
Increase the number of speakers in the compartment, and correspond the place of the speaker that display the auditory information and the landmark.
Moreover, presentation of visual information is also an effective method.
Case 5
Suggestion
It would be even more fun if not only for cars but also for the system could be used as a mobile device. effect Detailed exploration is possible with a mobile device, after searching a wide range by car. In order to attend to the sounds more actively, it is effective to get off the vehicle. That action will make the local culture and the social environment more
