  • The Evolution of More Massive Stars

    Learning Objectives By the end of this section, you will be able to: If what we have described so far were the whole story of the evolution of stars and elements, we would have a big problem on our hands. We will see in later chapters that in our best models of the first few…

  • Understand the science of acoustics

    Acoustic engineering jobs often require technical skills and knowledge. It’s helpful to understand the acoustical concept of frequency bands and the effect that noise can have on others. You can also develop an understanding of sound waves, including knowledge of how sound can travel through walls. Having some knowledge of the human ear and how…

  • Reduce building vibrations

    Low-frequency sounds can cause strong vibrations within buildings and structures. Acoustic engineers may reduce vibrations by coating metal parts with a damping material or implementing acoustic absorption techniques. In this role, you may investigate the source and cause of vibrations, including vibrations in residential, industrial and office buildings.

  • Enhance entertainment sound experiences

    Acoustic engineers might implement solutions to enhance the sound experience at entertainment venues. These engineers may optimize the acoustics of theaters and auditoriums to help create a more enjoyable experience for audiences. Reflected sounds or reverberations from the walls, ceiling and floor may disrupt live performances, so acoustic engineers often use their expertise to add…

  • Measure noise levels

    Acoustic engineers may measure noise at workplaces to help businesses maintain safe sound levels. Reducing and mitigating loud noise in the workplace can help prevent hearing loss among employees who work in those settings. Acoustic engineers may use sound level meters, noise dosimeters and octave band analyzers to measure noise in decibels. You may also…

  • Implement noise-reduction solutions

    Acoustic engineers may develop solutions to reduce noise pollution. As an acoustic engineer, you could create noise barriers to control sound and implement soundproofing techniques for making walls and windows soundproof. You could also implement acoustic techniques to reduce the sound levels in industrial buildings that use heavy equipment and machinery.

  • What is an acoustic engineer’s work environment like?

    Working as an acoustic engineer might involve inspecting or working on noisy sites such as construction zones, factories or other industrial sites. Acoustic engineers may work outdoors in different weather conditions and the work may include standing for long periods. Many acoustic engineers work full-time, completing 38 hours per week. Part-time employees may work less.

  • salary of an acoustic engineer?

    According to data from Payscale, the average salary for an acoustic engineer is $66,129 per year. You may be able to earn more than this depending on your level of experience, qualifications and location. For example, an acoustic engineer with a master’s degree may earn a higher salary than an entry-level employee.

  • What are musical intervals ?

    An interval is the ratio in frequency between musical notes. Theseintervals are sometimes called a second, third, fourth, fifth etc.which refers to the position on the scale that the note is to be found.In the scale of C major: C D E F G A B C, the note ‘E’ is the thirdnote of the…

  • Why does blowing over a bottle make a note ?

    Resonance in acoustics occurs when some mass-spring combination issupplied with energy. Many musical instruments rely on air resonanceto improve their sonority. If you blow across the mouth of a bottle youcan often get a note. The bottle behaves as a Helmholtz resonator. Themain volume of air inside the bottle is analogous to a spring, whilstthe…
