Abstract(J)車外騒音用路面は一定の規格に基づき施工されているが、その性状が規格内であっても実用面で有意な差を生じることが知られている。今回、性状違い4種の路面とパターン違いのタイヤを用いて惰行走行時の車外騒音分析し、路面性状と、タイヤパターンの要因を明確にできたので報告する。

Abstract(E)The road surfaces used in the testing of pass-by noise are installed in accordance with fixed standards. In this report, we explain the results of their comparative analysis of the pass-by noise levels of tires with varying patterns during coasting on four different types of test road surfaces with varying characteristics, through which we have shed new light on several influencing factors with respect to road surface characteristics and tire pattern.

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.
