acoustic: Pertaining to sound and hearing.
colleague: An individual who works with another person, such as a colleague or team member.
Develop: To come into existence naturally or through human intervention, such as through manufacturing.
size: Descriptive characteristics that can be measured, such as length, width, and time.
Helmholtz resonator: Named after 19th century German physicist Hermann von Helmholtz, this is essentially a hollow container with short, narrow necks. For each specific volume, this resonator produces a sound of a single frequency. Examples of Helmholtz resonance include hand clapping and the sound produced by blowing across the neck of a soda pop bottle. Even car mufflers can act as Helmholtz resonators.
Mechanical Engineer: An individual trained in a discipline that uses physics to design, construct, and/or test devices by studying motion and material properties.
mechanism: The process by which something operates or functions. It could be a spring releasing something from one location to another. It could be the contraction of the heart muscle that circulates blood throughout the body. Researchers often investigate the mechanisms behind actions and responses to understand how things work.
Model: A representation of real-life events (often done on a computer) developed to predict one or more outcomes. Or an object intended to demonstrate how something functions to others.
Physical: (adj.) Referring to what exists in the physical world, as opposed to in memory or imagination. It also describes the properties of a material due to its size and non-chemical interactions (such as when one object collides with another).
Physics: The scientific study of the properties and interactions of matter and energy. Classical physics explains the properties of matter and energy based on concepts like Newton’s Laws of Motion. Quantum physics is a later field of study that provides a more accurate description of the movement and behavior of matter. Scientists working in these areas are known as physicists.
pitch: (In acoustics) A term used by musicians for sound frequencies to describe how high or low a sound is. It is determined by the vibrations that create the sound.
Pressure: The force applied uniformly to a surface, measured as force per unit area.
silicone: A heat-resistant material used in various applications, such as rubber-like materials that create waterproof seals around windows and aquariums. Some silicones act as lubricants, similar to grease in vehicles. Most silicones, a type of polymer molecule, consist of long chains of silicon and oxygen atoms.
Sound waves: Waves that transmit sound. Sound waves consist of alternating regions of high and low pressure.
Unique: Something that is distinct from others, the only one of its kind.
It vibrates: To shake rhythmically or move back and forth continuously and quickly.
