Rating that represents a floor/ceiling assembly's ability to block impact sound transmission.

Standard method to measure acceptable background noise levels in different types of spaces.

Repetitive echoes resulting from parallel reflective surfaces; disrupts speech and music clarity.

Balance between sound reaching the listener directly from the source and sound reflecting off surfaces; affects clarity and intimacy.

Measure of sound intensity; important for setting acceptable noise levels within a space for comfort and functionality.

Adding background noise to reduce the perceptibility of unwanted sounds in open or crowded environments.

Measure of a ceiling system's effectiveness in blocking sound transmission between rooms.

Use of materials that transform sound energy into heat, minimizing reflections for better acoustic quality.

Use of electronic systems, like sound reinforcement and signal processing, to enhance or alter the acoustics of a space.

Preventing sound from transmitting from one space to another; uses materials and structural techniques to block sound.

Resonant sound waves that amplify at specific room dimensions, potentially overpowering other frequencies.

Computer simulations to predict the acoustic performance of a space; guides the design and material choices before construction.

Extent to which spoken words are unintelligible or inaudible to unintended listeners.

Spread of sound waves in different directions; prevents echoes and dead spots using irregular surfaces or diffusers.

The clarity of speech in a given space; affected by RT, background noise, and sound pressure levels.

Design of heating, ventilation, and air conditioning systems to minimize noise while maintaining functionality.

The process of creating audible sound files that represent the acoustic characteristics of a space.

Devices or constructions designed to absorb low frequency sound to control reverberation and standing waves.

Adjusting RT to suit the function of a space; materials that absorb or reflect sound to manage echoes.
