Quick comparison
| Type | Typical noise | Best for | Pros | Cons |
|---|---|---|---|---|
| Battery (cordless) | ~65–75 dB | Most homes | Quiet, mobile, easy start | Runtime depends on battery |
| Corded electric | ~70–85 dB | Small yards near outlets | Light, unlimited runtime | Cord management |
| Gas | 95–105+ dB | Heavy brush, acreage | Continuous power | Loudest, maintenance |
Decision guide
- Small yards and light trimming
- Choose 20–40 V cordless with round, thinner line
- Medium lawns with tougher edges
- 40–60 V cordless, brushless motor, variable speed
- Heavy weeds or fence lines
- 60–80 V cordless with thicker, round or twisted line; work in bursts
Trimmer line and noise
| Line type | Noise | Best use |
|---|---|---|
| Round | Lower | General trimming and edging |
| Twisted/spiral | Lower than square | Taller grass; better airflow |
| Square/serrated | Higher | Aggressive cutting on tough stems |
| Thickness | Thinner is quieter | Match to tool specs; thicker cuts faster but adds noise |
- Keep line fresh. Brittle line slaps and whistles more.
- Cut to the proper length; long line increases drag and noise.
Spool size and yard size guide
| Spool size | Typical line length | Where it fits |
|---|---|---|
| Small | Shorter runs; frequent refills | Patios, decks, small yards |
| Medium | Standard runs; weekly trimming | Most suburban lawns |
| Large | Longer runs; fewer refills | Bigger lots and fence lines |
Runtime planning (battery)
- Watt hours = volts × amp hours (sum if two packs)
- Runtime ≈ watt hours ÷ average draw (watts)
- Practical tips
- Keep a spare pack ready; rotate packs
- Use lower speed for edging on hard surfaces
- Store batteries at room temperature
Quiet use techniques
- Feather the trigger; full blast only for thick spots
- Keep distance from walls and metal edging to reduce echo
- Trim when grass is dry; wet grass drags and gets louder
Maintenance for quieter trimming
- Keep the guard, head, and vents clean
- Replace worn bump knobs and spools; rattles get louder fast
- Check fasteners and handle clamps; tighten before each session
FAQs
Is 65–70 dB quiet for a trimmer?
Yes for residential use. It is far below gas levels. Use lower speed near hard surfaces to reduce echo.
What line thickness is the quietest?
Thinner, round line is usually quieter. Stay within the tool’s recommended range and avoid brittle, old line.
Does bump feed make more noise than auto‑feed?
Loose bump knobs or worn parts can rattle. Keep parts tight and replace worn components to minimize chatter.
Are blade attachments quieter than line?
No. Blades can be harsher on hard edges and reflect sound. Stick with line types for quieter results.
