Surface Tension and Liquid Viscosity Essay My report is dealing with liquid viscosity and how they are used to help us measure liquids and gives us the accurate temperature that we have today - Viscosities: Surface Tension and Liquid Viscosity Essay introduction. I first want to talk about viscosity and the role it plays in all of our lives.

Most sound level meters provide readings in A, C, and Z-weighted decibels and must meet international standards such as IEC - Examples[ edit ] The lower limit of audibility is defined as SPL of 0 dB, but the upper limit is not as clearly defined.

Investigating the viscosity of liquids

Human hearing does not have a flat spectral sensitivity frequency response relative to frequency versus amplitude. Because the frequency response of human hearing changes with amplitude, three weightings have been established for measuring sound pressure: A, B and C.

A-weighting applies to sound pressures levels up to 55 dB, B-weighting applies to sound pressures levels between 55 dB and 85 dB, and C-weighting is for measuring sound pressure levels above 85 dB. A-weighted sound pressure level is written either as dBA or LA. Unweighted sound pressure level is called "linear sound pressure level" and is often written as dBL or just L.

Some sound measuring instruments use the letter "Z" as an indication of linear SPL. In the case of ambient environmental measurements of "background" noise, distance need not be quoted as no single source is present, but when measuring the noise level of a specific piece of equipment the distance should always be stated.

Because of the effects of reflected noise within a closed room, the use of an anechoic chamber allows for sound to be comparable to measurements made in a free field environment.Extracts from this document Introduction.
