Errata & Supplements to the book

Updated 15 January 2004. We have more material for this page but have not yet had time to put it in. Come back soon.

It is unavoidable that there are several errors in such a comprehensive book. The following lists the errors known to the authors as well as several supplements:

Page 13 and 525:
Just after the book was submitted for printing, the EU Parliament and Council issued a new Directive “relating to the assessment and management of environmental noise”. It would have been worth mentioning on these pages. The Directive has the number 2002/49/EC and was published in the Official Journal of the European Communities (OJ) No. L 189/12, 18.7.2002. It can be downloaded via a link provided here, see page 525 below.

Page 19, left column, 4th paragraph, lines 3-4:
The final version of the EU Directive (published in June 2002, see page 13 above) defines the daytime period as 12 h and the evening period as 4 h.

Page 37, caption for Fig. 4.14:
The third sentence mentions "each green bar". The bars referred to are yellow/red.

Page 39, 6th line from top:
WP-NREV shall read WP-NERV

Page 92, left column, the equation:
In the equation, “ar” should read “ax”.

Page 222, Fig.10.25, figure caption:
Delete “(left)”. Before finalizing this chapter we had also a right part of the figure. We forgot to change the caption when this part was deleted.

Page 273, subchapter 11.15, 4th paragraph, line 9:
“Intesity” shall read “intensity”.

Page 281, Fig. 12.5:
In the figure caption, the sentence reading “PA = porous asphalt, SMA = stone mastic asphalt” (which was copied from Fig.12.4 in which it is correct) shall read “KH = Kunstharz Beschichtung = Epoxy surface, SD = Surface dressing”. Further, in the insert box in the figure, the term “grinded concrete” is not very good since it may be mixed with another type of grinding treatment often applied to cement concrete surfaces. This surface is in fact “polished” by a special polishing machine.

Page 320, section 14.9.4, first two paragraphs:
The sound pressure waves were averaged as sound waves and not as spectra as implied in the text (the spectrum loses the phase information which is the essence of this averaging technique). The sound wave average contains all information on both amplitude and phase and the final average is converted to a spectrum.

Page 328-329, Table 15.1 (on both pages):
There are two Table 15.1. The one on page 329 should be Table 15.2. All later tables in Chapter 15 should be renumbered.

Page 330 and 346, Table 15.2 (on both pages):
There are also two Table 15.2. The one on page 330 should be Table 15.3 and the one on page 346 should be Table 15.4. All later tables in Chapter 15 should be renumbered.

Page 384, subchapter 17.3:
The reference to [Walker, 1981] has been lost here. Walker’s PhD Thesis should be referenced here since he compared CB with DR measurements in an advanced way. This reference is listed in the References (Chapter 34).

Page 414, subchapter 19.3.3, the formula:
This is intended for asphaltic surfaces only. For other surfaces, for example cement concrete, we suggest u = 0.

Page 415, subchapter 19.3.4, line 5:
Section 11.8.5 is mentioned; it shall be section 11.12.5.

Pages 477-478, Section 22.13 (Case Study: The Netherlands):
We are fortunate to have got permission by our Dutch friends to publish on our website two Inter-Noise papers describing the great  Dutch Noise Innovation Program Road Traffic (IPG) and the Roads to the Future Program (WnT). This information is much more up-to-date than the section we wrote in 2002. Currently, these programmes do not yet have any own websites, so this information (in English) is rather unique. Click on this link to go to this web page.

Page 478, Fig. 22.24, figure caption:
The reference here is incorrect. Mr Kuijpers did not supply this figure to us; it was Mr Jan Hooghwerff at M+P. The road described in the figure was designed by Mr Wim van Keulen at M+P raadgevende ingenieurs bv (same company as that of Mr Kuijpers) for the Dutch road constructor KWS. We are grateful to Mr Van Keulen and regret that we mixed names here.

Page 525, right column, section 28.2:
You can download the EU Directive from
This site also has the Environmental Noise Directive 2002/49/EC (see page 13 above).

Page 567, left column, third paragraph:
The link to the ITRD database has changed and is now:,2340,en_2649_201185_2742934_1_1_1_1,00.html
ITRD offers a “Transport CD” that is updated four times per year (the database itself is updated each month). Access to the database is based on a “pay per view” process.

Page 615, “Rubber (in road surfaces)”:
The page number 474 shall be changed to 473.

We apologize for these errors. Book readers noticing any other errors are kindly requested to notify us of them.
