Abstract(J)	キャビンに接する各パネルからの音響インテンシティ量をSEAベースでモデル化し、パネルから耳位置音までの実験的な伝達係数を用いることで、車室内高周波空気伝播音を予測する手法を確立した。これにより、ボディおよびトリム部品のスペック検討を進めるために必要な耳位置での予測が、実用精度で可能になった。 Translation
Abstract(E)	The acoustic intensity from the inner body panels was modeled based on SEA. The addition of the acoustic transfer function to this model makes high-frequency airborne sound in the vehicle interior predictable. That enables to predict the acoustic performance of the body and trim components with practical accuracy.

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".
