Hi Stuart,

I don't have a copy of the particular noises you mention, but I can offer you another collection of noises that may or may not be helpful, a "sound texture corpus" of 200 sound recordings, which we analysed for this paper:

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0238960

In the paper we looked at the distribution of statistical features of these sounds, and found that these could be captured to a large extent by a modest number of principal components. We think that it may (or may not) be helpful to use principal component dimensions to choose a set of noises that is in some sense "representative" in that it can sample a wide range of the expected variability of sound textures using a manageable number of sound exemplars.

The noises are free to download here:

Hope you are doing great and keeping your trademark smile in fine shape.

Best wishes,

Jan

Anyone have a copy of:

Vestergaard, M. 1998 . “The Eriksholm CD 01: Speech signals in various acoustical environments,” Report No. 050-08-01, Oticon Research Centre Eriksholm, Snekkersten.

they could share. TBH, I'm more interested in the CD itself as it has a selection of noises (cafeteria noise, car interior noise, and noise from a bottling hall) that would be interesting to use for some speech-in-noise studies we are planning. These noises were mentioned in:

Kjems, U., Boldt, J. B., Pedersen, M. S., Lunner, T., & Wang, D. L. (2009). Role of mask pattern in intelligibility of ideal binary-masked noisy speech. Journal of the Acoustical Society of America, 126(3), 1415-1426. https://doi.org/10.1121/1.3179673

I am also pretty sure I have seen the noise from a bottling hall being used in other studies from DTU.

Thanks for any help!

Yours - Stuart
