Perception & Measurement of Odors Compared To Noise

Is it possible to draw an analogy between the perception of odors and noise? Both the public and professionals are familiar with the noise measurement expressed in decibels. Noise is also formed of frequencies (treble or bass). Series of sounds can create melodies that would trigger emotions.

Odors Measurement – Olfactometry vs. Chemical Analysis

There are several odor measurement methods. Characterization via chemical analysis and sensory or olfactometric characterization have advantages and drawbacks. Despite the known benefits of the conventional chemical analysis characterization (accuracy, reproducibility, etc.), olfactometric measures are generally preferred due to the characteristics of the measured parameters

New Guidelines Set for Odor Studies

In many ways, odor modelling is not very different from dispersion modelling for criteria pollutants. The same basic models in use and referenced by U.S. EPA Guidelines and clearinghouse memorandum.

Odor Modeling Assessment Considerations

Odor nuisance standards do not preclude the occurrence of odors that are above the odor threshold limit. The nuisance standard only precludes that the frequency cannot be such that a person cannot enjoy the use of his property or conduct business. When conducting an odor impact assessment, one needs to define whether this translates to a 0.1, 1 or 10 percent exceedence criteria.
