I will fix noise, hum and interference issues in your audio amplifier pcb design
Audio Electronics Engineer PCB Designer Amplifier Bluetooth Circuit Specia
About this Gig
Hum, buzz, hiss, and RF interference in your audio PCB are not random they have specific causes and specific fixes. I will find them and eliminate them.
I will analyze your audio amplifier PCB layout and schematic, identify every source of noise and interference, and deliver a corrected design that is quiet, clean, and interference-free.
Noise problems I solve:
- 50Hz/60Hz mains hum and ground loops
- High frequency switching noise from power supply
- RF interference from nearby wireless devices
- Crosstalk between audio and digital signal traces
- Poor grounding and star ground errors
- Insufficient decoupling and bypass capacitors
- Trace routing causing EMI pickup
What you get:
- Detailed noise source analysis report
- Corrected PCB layout with proper ground planes
- Schematic fixes for decoupling and filtering
- Gerber files for the corrected PCB (Premium)
- Written explanation of every change made
A quiet audio PCB is not luck it is good engineering. Let me bring that to your design!

FAQ
What PCB design tools do you work with?
I work with KiCad, Altium Designer, EasyEDA, Eagle, and can review layouts shared as PDF or image files.
Can you fix a hum caused by a ground loop?
Yes, ground loop elimination is one of my most common fixes. I will redesign your grounding topology to eliminate it.
Do I need to share my full project files?
Ideally yes — schematic and PCB layout files give me the most to work with. I can also work from screenshots or PDFs.
Will you test the fix with simulation?
Signal integrity and noise simulations are included in the Premium package.
What if the noise is coming from the power supply?
I will identify that and include power supply filtering recommendations as part of the fix.
