High noise levels are an irritation and, at very high levels, a health hazard. Several new applications allow smart phone owners to turn their phone into a sound meter. A number are reviewed at healthyhearing.com.
For more about the connections between noise and health see the noise section of the Design for Health web site.
With growing interest in active transport practitioners and researchers have created a large number of tools to measure active transport behavior and environments. The following web sites provide lists or databases of such tools. If you want to measure AT, such sites can be a good place to start. Thye have been sponsored by such groups as the Robert Wood Johnson Foundation, the National Cancer Institite, and the Federal Highway Administration:
- Active Living Research Tools and Measures: A compilation of community audit, park audit, survey, tracking, and related tools for measuring physical activity environments and behaviors.
- National Collaborative for Childhood Obesity Research:(NCCOR) Measures Registry: A database of measurement tools including many related to measuring physical activity behavior and the built environment; oriented toward research applications: http://tools.nccor.org/measures/
- Standardized Questionnaires of Walking and Bicycling Database: A database with approximately 100 tools focused on physical activity: http://appliedresearch.cancer.gov/tools/paq/
- Toole Design Group: 29 case studies of measuring walking and cycling: http://www.pedbikeinfo.org/pdf/casestudies/PBIC_Data_Collection_Case_Studies.pdf

Recently I highlighted work of the National Collaborative for Childhood Obesity Research (NCCOR). a group spearheaded by the National Institute of Health, Centers for Disease Control, and Robert Wood Johnson Foundation. They have now released a new tool, or rather a registry of measures related to diet and physical activity: http://tools.nccor.org/measures/. I was part of the team on this project. My role was cataloging some of the physical activity measures, a mix of “questionnaires, instruments, diaries, logs, electronic devices, direct observations of people or environments, protocols, and analytic techniques.” Overall there are over 700 measures.

I’ve recently been involved creating a new survey for measuring transportation behavior, particularly walking and cycling. The Pedestrian and Bicycling Survey (PABS) is a mail out/mail back survey designed to be an inexpensive means for local governments to learn about nonmotorized transportation use in their communities.
An important component of the design of the PABS was creating a probabilistic sampling approach that would be relatively straightforward to administer and, if desired, could be carried out in house (within municipal agencies). While other sampling approaches—such as snowball sampling across the internet—can achieve a large number of responses, the probability of any person being asked to take the survey is not known making it a challenge to generalize from the sample to the wider population.

The National Collaborative for Childhood Obesity Research is a group spearheaded by the National Institute of Health, Centers for Disease Control, and Robert Wood Johnson Foundation. The Catalog of Surveillance Systems is a new product, also sponsored by the USDA. The catalog provides a searchable database of ongoing monitoring systems related to health. It includes both public systems such as the Census of Agriculture and National Vital Statistics System and private ones such as the Nielsen Homescan and InfoUSA.com. In all, 77 systems are represented.
