Spatial and temporal sampling methods for community noise surveys

Sampling Methods for Web and E-mail Surveys

This chapter is a comprehensive overview of sampling methods for web and e-mail (‘Internetbased’) surveys. It reviews the various types of sampling method – both probability and nonprobability – and examines their applicability to Internet-based surveys. Issues related to Internetbased survey sampling are discussed, including difficulties assembling sampling frames for probability sampling, cov...

Community noise annoyance risk in two surveys.

Two noise annoyance surveys were performed in Bratislava, the capital of the Slovak Republic, in a ten-year interval (1989-1999). This was a period of political and socioeconomic transformation as well as of changes in traffic management. Equivalent noise levels were assessed at the dormitory (exposed group) and in the residential areas (100 measuring stations) where another group of students (...

Reliability of sampling designs for spatial snow surveys

Spatial patterns are an inherent property of most naturally occurring materials at a large range of scales. To describe spatial patterns in the field, several observations are made according to a certain sampling design. The spatial structure can be described by the semivariogram range, and nugget and sill variances. We test how reliably seven sampling designs estimate these parameters for simu...
