Photography is trimming of spatiotemporal information of the real world. The clues to know behind the scene of photography will exist in the outside of the photo, such as the surrounding situation, the photographer's motivation, and the process of the shooting. We propose a photo media "Behind the Photo" showing behind the scene of photography. Our proposed method shows photography experience by presenting the frame and the taken photo on the spherical video. We believe that our method will provide a way for photographers to make their content more enjoyable and attractive, and help appreciators to understand the presented photos. In this research, we developed a camera device and a viewer for "Behind the Photo", and evaluated the experiences of photography and appreciation.

A survey was conducted to gather data for an assessment of the vocal noise level from children playing in nursery schools or other similar facilities. Ten nursery schools were surveyed; 5 locations in Setagaya Ward, Tokyo and 5 in Hachinohe, Aomori Prefecture. The surveys considered two cases: the noise levels while the children were playing in the yard, and those while they were playing inside. Measurements were taken over 10-minute intervals and the variables analyzed were equivalent continuous A-weighted sound pressure level ( called equivalent continuous noise level ), maximum noise level, percentile noise level, and frequency (1/1 and 1/3 octave bands). Additionally, at the first nursery school surveyed, a continuous measurement of the noise level was conducted for 24 hours to examine the conditions of measurements and the length of the analysis period. The noise level was found to be approximately 20 dB higher while the children were playing in the yard or in the pool than during other times of day, and that was about 30 dB louder than at night. In the nursery schools where the measurements were taken, the noise levels were also about 5 to 7 dB higher while the children were entering in the morning, which was not a dramatic difference. The equivalent continuous noise level measured 10 m from the center of a group of children playing in the nursery school yard was about 62 dB when there were 10 individuals and 74 dB when there were 100 individuals. However, it was possible for the noise to momentarily reach levels over 90 dB. The mean level of the vocal noise also increased by about 10 dB during music classes and when a microphone was being used. The frequency analysis of vocal noise from children indicated peaks of around 1000 Hz and 2000 Hz. There were linear decreases from these peaks at other frequencies. These values were higher than the pitches observed from conversations involving only adults. The effectiveness of a noise barrier installed within the nursery school grounds was estimated using the above results. Four cases were considered, where the height of the wall was varied from 2.0 m to 3.5 m. The wall was estimated to reduce the noise by 15 - 20 dB, which was considered to be sufficiently effective.

A questionnaire on neighborhood noise disputes was carried out to persons in charge of the noise problem in municipal offices in the whole country. A number of the answers was 479 and the recovery rate was 62%. Through the result, the conflict concerning a dog barking increases in small cities, and that is anticipated to increase in the future. There were arguments pros and cons about the regulation against the neighborhood noise. In the free description, it is mainly commented that the neighborhood noise dispute depends on the lack of the neighborhood association.

前年度の視覚障害者に対するインタビュウー調査結果により、建築音響の影響、すなわち空間の音の響きや壁面での音の反射性状が実際によく意識されており、屋内での歩行・行動のし易さに影響を与えているという結果が得られた。これらの具体的影響とその度合いを実際の歩行行動の中で確認し、その影響因子となる建築音響の物理量を究明するため、残響時間や空間の大きさ・形などの建築音響条件の異なる4つの空間において、視覚障害者と晴眼者(アイマスク着用)の歩行実験を行った。その結果、残響時間やSTI、IACC(両耳間相関係数)などの音響指標との直接の対応は確認されなかったものの、建築音響条件の影響が有意であること、また、細長く1次元的な音響空間では、広い空間より歩行時の方向感が良くなることが実験結果により確認された。更に、これらの結果は実験空間における実験結果であることから、実際の空間条件での実験検討として、空間ロビーやデパートなどの各種建物や施設内での歩行実験を行った。その結果でも、細長い空間と広い空間との識別、細長い空間での方向感の良さなどが実際に確認された。視覚障害者の歩行・行動に対する建築音響条件の影響については確認がなされたが、これを制御し,最適化を図って行くためには、具体的な影響因子の抽出が不可欠である。今後、さらに建築音響指標の範囲とその組み合わせの幅を拡げ、建築音響の影響メカニズムを明確化する予定である。
