Re: noise reduction rating and the max db for the qc35 and Nch700

Hello dennis_pham,

 

Welcome to the community, thanks for reaching out. 

 

Bose does not publish these specifications nor do we measure our products via these measures. The reason for this is that we believe such statistics do not add very much to an understanding of an audio product's acoustic characteristics and, even worse, can be misleading. Audio manufacturers make these measurements independent of industry standards, and in varying conditions.

Additionally, a single statistic is not a reliable measurement of a product's performance. One could, for instance, find a very expensive system with exactly the same specifications as a much less expensive system. On paper, the two would appear identical. The difference in performance, however, would be significant. A better approach, we feel, is to listen to the product. We strongly urge you to make your own comparisons as Noise Cancelling performance is perceived differently by different people.

 

If you have any further questions, do let us know and we will do what we can to assist you. 

 

Kind regards,
