Sound Designer (subcontractor) · Dukinfield, UK · Aug 2026 – now

I work with 344 Audio, a UK sound effects company, on sound design, editing, mixing and delivery for its projects. I also published 56 sound effects library packages on itch.io for its 344 SFX label, and wrote the team’s step-by-step publishing guide (SOP) so every package is prepared the same way.

Acoustics

Measuring what we hear

My MSc in Acoustics at the University of Salford: real projects, my own calculations, and tools you can play with. Everything below comes from my reports.

MSc dissertation · 2025–26 · Supervisor: Dr Deepak Akiwate

Data-driven drone noise modelling and prediction

Small drone propellers make strong tones at the blade passing frequency and its harmonics. I built a physics-informed model that predicts these tones: a physical source model gives a baseline level, and a random-forest model learns what the physics misses. Each propeller was tested on data the model had never seen.

InputsBlade geometry, thrust, RPM, harmonic, observer angle

Physics modelThrust-constrained radial source → baseline SPL

Random forestLearns the measured-minus-physics residual

Room Acoustics · coursework

Designing a teaching control room

A 6.0 × 4.2 × 2.7 m control room in Salford's SEE building, for stereo and 5.1 teaching. I chose the room ratio, predicted the modes and early reflections, then designed bass traps, broadband absorbers and a rear-wall diffuser to create a reflection-free zone at the mix position.

Listen in this room Sound with pulse

The left speaker fires a pulse. Each wall acts like a mirror, so its reflection travels from an image source behind the wall. Drag the listener and the arrival times update.

Loudspeakers & Microphones · Immersive Sound Reproduction

Loudspeaker modelling and design

In MATLAB I modelled an eight-driver soundbar (Peerless TC5FB00-04, 40 mm spacing) with a Peerless XLS-P830452 woofer in a 10 litre sealed box, joined by a 4th-order Linkwitz–Riley crossover at 250 Hz. For immersive sound I designed a gramophone-style two-way speaker with a horn tweeter and a transmission line.

Frequency1 kHz

Turn down the outer drivers (my fix)

Listen at

The beam is broad at low frequency, narrows through the mid band, then breaks into lobes and nulls at high frequency. Simplified view: eight ideal point sources at 40 mm spacing; the taper weights here are illustrative.

Max deviation above 1 kHz at 30°28.71 → 24.61 dB

Mean deviation above 1 kHz at 30°14.55 → 10.37 dB

Measured in my model: original design → after reducing the outer drivers.

Principles of acoustics & vibration

Machine on springs: finding its natural frequency

From a measured impulse response I identified a 100 kg machine on resilient mounts. Press play to see the decay my values predict.

f_n ≈ 11.2 Hzζ ≈ 0.067k ≈ 4.98 × 10⁵ N/mc ≈ 948 Ns/m

I also calibrated a measurement chain (2.87 Pa/V) and found 78.57 dB SPL at the microphone.

Measurement Analysis & Assessment

Vibroacoustics: blocked forces

Impact-hammer mobility measurements on a coupled source–receiver assembly, then blocked forces to predict its vibration. Adding rotational terms improved the prediction.

Validation error (dB). Best coherence 0.9817; repeat impacts agreed to a median ratio of 0.986.

Environmental Noise Measurement & Modelling

Aircraft noise next to Manchester Airport

An acoustic design statement for flats at Runway Visitor Park, using ProPG and BS 7445-1. Hover a point to compare the average and the loudest event.

Façade points were most exposed (up to L_AFmax 89.2 dB), so I recommended quiet-side layouts, better glazing and ventilation.

Noise & Vibration Control

Heat pump noise and silencer design

Checked an air source heat pump against the MCS 020 limit, sized a duct silencer for about 10 dB at the blade passing frequency, and designed a 2 m barrier for at least 8 dB(A) insertion loss.

Predicted level at each neighbour before mitigation (with +3 dB façade reflection), against the 37 dB limit.

DSP & Machine Learning

Filters, reverb and neural networks

Comb and all-pass filters as a simple room reverb, FIR and IIR filter design, and a neural network to map a non-linear system, all in MATLAB.

A feedback comb filter's response: the building block of digital reverb.

About & contact

Let's work together

I grew up learning Carnatic music, and that led me into audio. I started out mixing live concerts, moved into the studio, and then into film post-production. Now I am adding the science behind the sound with an MSc in Acoustics.
