Acoustical Engineering is a sub-section of engineering, a science of designing and building structures and machinery - but this area deals specifically with sound and noise vibration.
What Does an Acoustical Engineer Do?
Acoustical Engineers design and construct buildings (structural and interiors) and machinery, amongst other things, that are concerned with the science of sound. Acoustical Engineers may work with engineers in other areas and other construction professionals where sound improvement or noise reduction is a major priority. Sound pollution is one of the lesser-understood (at least in the public perception) areas of environmental science - it can affect wildlife to a certain degree and contributes to an area's desirability or otherwise. An Acoustical Engineer assesses the noise impact of any construction.
Where Does an Acoustical Engineer Work?
They will often work in the construction industry - either for private businesses or in civic works for local or state government. This means they will be involved in the design of sports stadium and arenas and recording studios to improve how sound carries, but may also look at reducing noise interference for local residents. With noise pollution having an impact on quality of life, their job is to come up with designs other than the functional or aesthetic. This also means building interiors - improving insulation in multi-family housing and apartment blocks.
They may also work as environmental consultants. The impact of noise, either temporary or permanent, due to the building of a new road, new residential, commercial or industrial zone will all consult an Acoustical Engineer to ensure there is minimum impact. Others are involved in designing medical acoustic equipment such as ultra-scan.
Most work full-time for an organization, though some prefer the freedom as working on a freelance consultancy basis.
What Is the Average Acoustical Engineer Salary?
The job title “Acoustical Engineer” falls within a broad category of engineering professions Entry-level jobs can typically start around the $67k salary mark with top end jobs reaching around $119k. This will vary by state, but also by specialty and type of employer (private, public, freelance or employed).
The state that employs the most people in this industry is California - typically in the world of TV and movie entertainment, and music. There are approximately 10,800 Acoustic Engineers in the US, around 3,300 of them work in California. The next biggest state is New York. The national median annual salary is $53,520; the mean hourly payment rate is around $32.31. The nature of the labor market means these figures vary wildly from state to state but an Acoustic Engineer working and living in California or New York can expect to earn north of $80,000.

What Is the Job Demand for Acoustical Engineering?
Acoustical engineers are in demand, mostly in the environmental sector, and over the next 5 years considerable growth is expected. Some figures project an increased demand for Acoustical Engineers at around 10% - higher than standard engineering jobs. With local, national and international standards on noise pollution, graduates can certainly expect to find work in this area with relative ease. You may even work in environmental science assessing the impact of noise pollution on wildlife.
The biggest growth area is as sound engineers in the entertainment industry. The need to improve sound quality within recording studios and entertainment arenas is a large part of this, but also is the need to reduce the impact on neighboring residential areas.
What Are the Education Requirements to Become an Acoustical Engineer?
There are few degrees specializing in acoustical engineering. Your best option is to study an undergraduate degree in engineering and specialize later on. Students need to have a high proficiency of hard sciences, especially math and physics. Electrical engineering will be essential to your undergraduate degree if you wish to go on to further study.
As Engineering is a highly sought qualification (one of the STEM subjects), you will not struggle to find relevant employment with a BS/BA. However, to improve your employability chances and make yourself more marketable, you should study for a postgraduate qualification. Most good entry-level jobs will require a master's degree. If you intend to go into the academic side of engineering such as teaching and / or research, you will certainly need a Doctorate.
