Comfort Flashcards
The sound pressure limits of the octave band spectra ranging from 63 Hz to 8000 Hz.
Noise criteria (NC)
The sense of smell.
Olfaction
An independent, non-governmental international organization that develops consensus-based, market-relevant standards for worldwide use.
International Organization for Standardization (ISO)
An enacted law that prohibits discrimination against persons with disabilities and ensures equal opportunity in employment, state and local government services, public accommodations, commercial facilities, and transportation.
Americans with Disabilities Act (ADA)
A person’s perception of air quality within an environment based on their sense of smell.
Olfactory comfort
The pressure variation associated with sound waves, usually measured in decibels (dB). Also known as acoustic pressure.
Sound pressure level
A laboratory method for determining sound transmission through a wall.
Sound transmission class (STC)
A graphical representation of the properties of air at various conditions.
Psychrometric chart
The science of adapting objects, spaces, and processes, such as workstations and workflow, to accommodate people’s capabilities in a safe and efficient manner.
Ergonomics
Energy composed of pressure waves, or vibrations, that travel through the air or another material and produce an audible signal when they reach a person’s ear.
Sound
The study of sound and the properties of a space or building that determine how sound is transmitted or reflected within it or through it.
Acoustics
The average value that determines the absorptive properties of materials.
Noise reduction coefficient (NRC)
A field test for determining the sound transmitting abilities of a wall.
Noise isolation class (NIC)
The time it takes for sound to decay, expressed in seconds.
Reverberation time
A unit of measurement for sound that is a logarithmic unit in which an increase in 10 decibels equals an increase by a factor of 10.
Decibel (dB)
An injury or condition that affects the body’s movements or its muscles, bones, tendons, nerves, or ligaments.
Musculoskeletal disorder
The use of electronic devices to generate low-level background noise in order to mask sound distractions.
Sound masking
The mathematical and graphical study of the properties of air.
Psychrometrics
The condition of satisfaction with the thermal environment
Thermal comfort
The ability of occupants to choose their own work space within the office or workplace.
