5 Common Sound Issues at Events (And How to Avoid Them)

At Sonic Sound & Lighting, we’ve powered hundreds of weddings, corporate events, community festivals, and live performances across the Hunter Valley and Newcastle region. While great sound can elevate any occasion, a few recurring audio problems tend to spoil the experience for many organisers who try to manage it themselves.

In this guide, we share the 5 most common sound issues we see at events — and, more importantly, exactly how to avoid them.

1. Microphone Feedback (That Annoying High-Pitched Squeal)

The Problem:
Feedback occurs when a microphone picks up sound from the speakers and loops it back, creating a loud, piercing squeal. It’s embarrassing, disruptive, and can damage equipment or hearing if it spikes suddenly.

How to Avoid It:

Position speakers in front of microphones and use directional mics (cardioid or supercardioid patterns).
Keep microphone volume as low as possible while still achieving good gain.
Use graphic EQ or feedback suppression tools on the mixing console.
Proper soundcheck before guests arrive is essential.

Pro Solution: Our technicians use premium Sennheiser wireless systems and expertly tuned Allen & Heath consoles with real-time feedback management. We know the sweet spots for every venue type in the Hunter region.

2. Uneven Sound Coverage (Loud in Some Spots, Quiet in Others)

The Problem:
Guests near the speakers are overwhelmed while those at the back strain to hear. This is very common in long or oddly shaped rooms, outdoor areas, and venues with pillars.

How to Avoid It:

Choose speakers with appropriate dispersion patterns for the space.
Use multiple speakers or delay towers for larger areas.
Angle and position speakers correctly (not just pointing straight ahead).
Consider line array or well-designed point source systems for better throw and consistency.

Pro Solution: Our Celto Acoustique ISORAY and full PA systems are chosen and positioned by experienced techs to deliver even, natural coverage. We often combine them with our mobile trailer stage for fast, effective outdoor deployments.

3. Distortion and Muddy Sound

The Problem:
The audio sounds harsh, crackly, or boomy. Bass overwhelms everything, or vocals get lost in the mix. This usually happens when a system is underpowered and pushed to its limits.

How to Avoid It:

Match the power and size of your system to the venue and crowd size.
Use quality subwoofers with proper crossovers (typically around 80–120 Hz) to keep bass tight and controlled.
Set appropriate input levels and use compression/limiting wisely.
Avoid cheap amplifiers and speakers that distort easily.

Pro Solution: Our Celto Acoustique systems with dedicated subwoofers are tuned for clean, powerful performance — maximum bass impact without mud or feedback into the stage area.

4. Wireless Microphone Dropouts and Interference

The Problem:
Microphones cut in and out, especially during key moments like speeches or performances. This is increasingly common due to crowded radio frequencies and venue Wi-Fi.

How to Avoid It:

Use professional-grade wireless systems with reliable frequency agility.
Perform a proper RF scan of the venue before the event.
Keep antennas clear of obstructions and use antenna distribution systems for multiple channels.
Have wired backups ready for critical roles.

Pro Solution: We rely on Sennheiser G4 500 Series wireless systems known for stability. Our techs scan frequencies on-site and monitor during the event to ensure zero dropouts.

5. Insufficient Volume or Lack of Clarity (Especially Outdoors)

The Problem:
The system can’t get loud enough, or sound gets lost in wind, traffic, or ambient noise. Vocals lack presence and music feels weak.

How to Avoid It:

Select a system with enough headroom (extra power) for the environment.
Use windshields on outdoor mics and position speakers to project toward the audience.
Optimise EQ for the space — cut problematic frequencies and boost where needed.
Consider adding more speakers or subs rather than just turning everything up.

Pro Solution: With years of experience in Hunter Valley outdoor events (including windy community festivals), our team knows how to design systems that cut through noise while remaining clear and comfortable.
