ACOUSTICS SPL test over an 8-hour period 60 50 40 30 20 10 0 Time Figure 6: A graphical representation of the SPL Test.
Following the development of the SPL meter, the device was tested over an eight-hour period in a test environment (not in a hospital). The data was then extracted from the SD card, and converted to a graphical representation, as seen in Figure 6.
As the graph shows, the device was working and tracking the data over the
About the authors Elise Guillemot
I have recently completed a Master’s in Mechanical Engineering degree with Distinction at the University of Portsmouth. In my third year of study I completed my dissertation on a Comparison of helicopter rotor blade tips with regard to lift and drag, and have worked on various projects throughout my time at university. During my free time I enjoy swimming and climbing, and I volunteer with the Royal Marine Cadets when I can. I hope to work with helicopters as an aircraft engineer in the near future, have applied to the Royal Navy as an Air Engineering Officer, and am currently undergoing the recruitment process.
Michael Semere
I am recently graduated Master’s student in Electronic Engineering with Distinction from the University of Portsmouth. While completing my course and developing my skills, I was heavily involved in participating with after-hours work at the University, aiding many students throughout their course with assignments and various projects. My personal dissertation during my third year was based around a system implemented within vehicles to prevent the early stages of drivers falling asleep, using facial detection methods and sensory equipment. I have had the opportunity to experience working in the defence sector, at a major defence contractor, with my ambitions leaning towards hardware/firmware engineering in the near future. Progressively, I am aiming towards completing my Chartered Engineering certification, and would hope to provide a platform to young and aspiring students from less fortunate backgrounds to proceed in a career in STEM.

I have recently completed a Master’s degree in Electronic Engineering at the University of Portsmouth. During my time studying at the University I have undertaken several projects. In my second year, I worked as part of a six-strong team to design and implement, from scratch, a fully autonomous ‘smart fridge’. In my free time I enjoy reading, swimming, and drumming. I also enjoy taking on projects outside the University curriculum to develop my programming and problem- solving skills, and spending time with my fellowship, IFCS. In the future I hope to be able to establish and own an engineering firm for young inquisitive minds like mine, in order to give those working at the company an opportunity and a space to express themselves and develop their ideas.

Local to the Portsmouth, I am a final year student completing my Master’s studies in MEng Electronic Engineering. I have a keen interest in many of the modules taught at the University, and hope to pursue a career in electronic engineering. Outside of University, I have a love and passion for music, playing with my band across the UK. My ‘ideal’ would be to be able to work in a job where I can combine both my passions.

eight-hour period. The SPL device developed can now be taken into a real scenario and tested over longer periods within the ICU environment. The plan is to run this project in future instances of the Group Project at the University of Portsmouth. The equipment currently being used would not suffice within an ICU ward, and it would be advisable in
