sentry_example: An example dataset as downloaded directly from a Sentry Noise...

In MarloesEeftens/NOISEtools: Helpful tools for environmental noise measurements and research.

Description

This .csv dataset was downloaded from an ExpoM-RF device which was sampling next to a busy road in Basel, Switzerland. The sampling interval was 1 second and the duration of the measurement was cut at 30min to minimize file size, yet give a real-world impression of the intermittancy ratio.

Usage

data("sentry_example")

Format

A data frame with 63 observations on the following variables.

Time (Date hh:mm:ss.ms)

Date and time at which the sample was taken.

L-Max dB -A

Maximum sound level in dB (A-weighted).

LEQ dB -A

Equivalent continuous sound level in dB (A-weighted), also known as time average sound level or LAT.

L-Min dB -A

Minimum sound level in dB (A-weighted).

Details

Data collected with the Noise Sentry RT by Convergence Instruments.

Examples

#Write the example .csv to a folder of your choice (please change pathname!):
my_filename1<-"V:/EEH/R_functions/NOISEtools/data/sentry_example.csv"
write.table(sentry_example,file=my_filename1,sep="\t",quote=FALSE,row.names=FALSE)
#Import using the import function:
my_sentry_file<-import_sentry(filename=my_filename1,prefix="SENTRY_")
str(my_sentry_file)
