Abstract(J)	電気自動車の室内におけるパワートレインノイズの音質を定量評価するために，複数の車室内音を用いてエキスパート14名によるシェッフェの一対比較法による主観評価実験を実施した．その結果と心理音響解析結果の対応を分析し，電動パワートレインノイズの音質評価指標を導出した． Translation
Abstract(E)	To quantitatively evaluate the sound quality of in-cabin powertrain noise in electric vehicles, a subjective evaluation experiment was conducted with 14 experts using Scheffé's paired comparison method. By analyzing the relationship between the subjective results and psychoacoustic analysis results, key sound quality metrics for electric powertrain noise were identified.

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".
