Abstract(J)	車載スピーカ開発のための車室内音場解析において，前報ではFMBEMによる解析結果と，実測結果を比較検討した．今回は，解析周波数範囲を20KHzまで拡大し，同様の音場解析を試みた．また，前報で課題としてあげた低域で解析結果が過大評価される点について確認の実験を行ったので報告する． Translation
Abstract(E)	In the vehicle interior sound field analysis for the development of in-vehicle speakers, the analysis results by FMBEM and the actual measurement results were compared and examined in the previous report. This time, we expanded the analysis frequency range to 20KHz and tried similar sound field analysis. In addition, we report the result that we conducted a confirmation experiment on the point that the analysis result is overestimated in the low frequency range, which was mentioned as an issue in the previous report.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
