| Why did I decide to compare the international standards? | ||||||
| Last year I prepared the procedure for calibration of speech audiometers (speech audiometry is carried out in a sound field in the Czech Republic). One of the most important things in this field is to have a quiet enough place where the testing can be performed. I found out that many of these rooms/booths in our country did not fit the criteria which were prescribed in the ISO 8253-2 standard. | ||||||
| I was curious about the differences between the ISO standards and the standards outside of the Europe. As I hadn't any information about maximum permissible ambient noise levels for audiometric test rooms in standards other than ISO 8253-1 and 2 so I decided to find out more about this problem. | ||||||
| First I would like to thank: | ||||||
| Mr. Tom Frank, USA | ||||||
| Mr. Michael Der, Canada - and his website | ||||||
| Mr. Erik Fry, Australia | ||||||
| Mr. Utz Richter, Germany | ||||||
| Ms. Janine Avison, UK | ||||||
| Mr. Timothy Sherwood, UK - and his website | ||||||
| Mr. Miloslav Gross, Czech Rep. | ||||||

| Note: | ||||||
| All values in the tables mean differences in dB SPL. | ||||||
| I'm very sorry that decimal commas (used in Czech rep.) are sometimes used in thetables instead decimal points. | ||||||
| If I use "ISO" or "ANSI" or "AS" it means ISO 8253-1,2,3 or ANSI S3.1-1991/1999 or AS/NZS 1269.4:1998. | ||||||
