Abstract(J)音質評価技術部門委員会WG3では第3報から時間的な音色変化を伴う燃焼音の評価手法の標準化に取り組んできた.本報告では,ディーゼル車の音質評価の最終報として,被験者実験に供試した音源の作成方法や実験結果をまとめ,音質評価の指針として主観評価と音質評価指標のラウドネス,シャープネスとの相関を確認した.

Translation

Abstract(E)WG3 in Sound quality technical committee has been working on the standardization of evaluation method on the sound quality evaluation of time-varying combustion noise. The method of signal synthesis and jury evaluation were developed and executed. As a result, the correlation between subjective and objective properties, especially loudness and sharpness, were investigated.

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.
