# How loud is a Tesla Optimus, and does it emit EMF?

**How Loud Is a Tesla Optimus? Does It Emit EMF?** · Last verified Jul 26, 2026. 3 sources.

**Undisclosed. Tesla has published no sound level or EMF emissions data for a home Optimus. Any consumer electronic sold in the US must meet the FCC's Part 15 emission limits, but that is a baseline every gadget meets, not an Optimus-specific disclosure.** Two questions live here, and both come back undisclosed for the robot itself, so the honest service is to hand you the real reference frameworks. On noise: Tesla has stated no decibel figure for Optimus, at work or idle. The useful scale is the appliances you already live with, a quiet dishwasher runs roughly 44 to 50 A-weighted decibels, and a robot vacuum roughly 55 to 65, loud enough to notice in a room but not disruptive. A humanoid with electric actuators would plausibly land somewhere in that everyday range rather than being silent or being a power tool, but that is an inference from comparable machines, not a Tesla measurement, and we label it that way. On EMF: every consumer electronic sold in the United States must meet the Federal Communications Commission's Part 15 limits on radio-frequency emissions, so an Optimus sold here would have to clear that federal bar like any laptop, router, or phone. That is a real, meaningful floor, but it is the floor every device meets, not a statement that Tesla has measured or published Optimus emissions. So the honest verdict is that the specific noise and emission numbers are absent, while the federal emission baseline would apply. We give you the real yardsticks and refuse to invent a decibel or emission figure Tesla has never stated. This is general information, not an acoustic or emissions assessment.

## Quick answers

- **Has Tesla stated how loud Optimus is?**: No decibel figure
- **What is the everyday noise scale?**: Dishwasher 44 to 50, vacuum 55 to 65 dBA
- **Would it meet US emission limits?**: Yes, FCC Part 15 baseline
- **Has Tesla published Optimus EMF data?**: Undisclosed

## Short answer

People ask this because a machine that lives in your home makes noise and runs on electronics, and both are fair to worry about. Both come back undisclosed for Optimus, so here are the real yardsticks. Noise: Tesla has stated no decibel figure, so the honest scale is the appliances you know, a quiet dishwasher runs roughly 44 to 50 A-weighted decibels and a robot vacuum roughly 55 to 65. A humanoid with electric actuators would plausibly land in that everyday range, but that is an inference, not a Tesla measurement. EMF: any consumer electronic sold in the US must meet the FCC's Part 15 emission limits, so an Optimus sold here would clear that federal bar like [any other connected device](/home-robots/optimus-can-be-hacked.md) such as a router or phone. That is a real floor, but the floor every gadget meets, not an Optimus disclosure. We give you the frameworks and refuse to invent a number Tesla has never stated. This is general information, not an acoustic or emissions assessment.

## What actually exists today

| What people ask about | Status | The reality |
| --- | --- | --- |
| A stated Optimus sound level | No decibel figure | Undisclosed. Tesla has published no decibel figure for Optimus, working or idle. There is no measurement on any record we can cite, so any specific loudness claim would be invented. |
| The everyday appliance noise scale | Dishwasher 44 to 50, vacuum 55 to 65 dBA | A real reference. Quiet dishwashers run roughly 44 to 50 A-weighted decibels and robot vacuums roughly 55 to 65. A humanoid with electric actuators would plausibly land in that everyday range, an inference from comparable machines, not a Tesla measurement. |
| US electromagnetic emission limits | FCC Part 15 baseline applies | A real floor. Any consumer electronic sold in the US must meet the FCC's Part 15 radio-frequency emission limits, so an Optimus sold here would clear that federal bar like any laptop or router. It is a baseline every device meets, not an Optimus-specific figure. |
| Published Optimus EMF or emissions data | Undisclosed | Undisclosed. Tesla has published no Optimus-specific emissions data beyond whatever certification US sale would require. So there is no measured emission profile for the robot on any record we can cite. |

## How to read the noise and EMF blanks

Two absences here get filled two wrong ways: noise gets imagined as either silent or deafening, and the federal emission floor gets read as an Optimus safety certificate. Here is how to hold each honestly.

- **The noise read: Everyday, most likely**: By analogy to appliances with electric motors, a humanoid would plausibly land in the dishwasher-to-vacuum range, noticeable but not disruptive. That is an honest inference from comparable machines, not a Tesla figure, and the real number is undisclosed.
- **The EMF floor: A baseline, not a badge**: Meeting the FCC's Part 15 emission limits is a real requirement any US electronic must clear, so an Optimus sold here would too. But that is the floor every gadget meets, not evidence that Tesla has measured or published Optimus emissions.
- **Why it matters: A machine you live beside**: Noise and emissions are the everyday, felt facts of a device that lives in your home, which is exactly why buyers ask. Appliance makers publish both. For Optimus, neither figure is on the record, so the felt experience is undefined.
- **Where it stands: Frameworks apply, figures absent**: We treat the appliance noise scale and the federal emission limit as real frameworks, and any Optimus-specific noise or emission figure as an honest absence. When Tesla publishes one, it becomes a dated line here.

## What would change this

We track this against [the Optimus entry on the registry](https://registry.deploy.report/models/tesla-optimus) so you do not have to. Any one of these fills a row, and each becomes a dated line the week it happens:

- Tesla publishes a sound level for Optimus, working or idle.
- Tesla or a certification filing publishes measured Optimus emission data.
- A home unit ships and independent testing measures its real noise and emissions.
- Scrutiny of home-device noise and emissions tends to sharpen after real incidents. Right now the verified record holds1 safety incidentfor home humanoid robots, and every new one is logged the week it lands.

## How we know this

The appliance and robot-vacuum noise ranges and the FCC Part 15 emission requirement are real, checkable frameworks; every Optimus-specific noise or emission figure is an honest absence. We present the noise range as an inference from comparable machines and the Part 15 limit as the baseline every US device meets, never as an Optimus measurement.

- [FCC Part 15: radio-frequency emission limits every US consumer electronic must meet](https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-15) (2026)

- [DEPLOY verified incident record](/robot-recalls-and-safety-incidents.md) (live)

If Tesla publishes a sound level or measured emission data for Optimus, or if you can show us we got a reference wrong, our corrections process logs the response on the record.

## Common questions

### How loud is a Tesla Optimus?

Undisclosed. Tesla has published no decibel figure for Optimus, working or idle. The honest reference is the appliances you already live with: quiet dishwashers run roughly 44 to 50 A-weighted decibels and robot vacuums roughly 55 to 65. A humanoid with electric actuators would plausibly land in that everyday range, but that is an inference from comparable machines, not a Tesla measurement. This is general information, not an acoustic assessment.

### Does a Tesla Optimus emit EMF or radiation?

It would emit the ordinary electromagnetic emissions any connected electronic does, and to be sold in the US it must meet the FCC's Part 15 emission limits, the same bar a laptop, router, or phone clears. That is a real federal floor. But Tesla has published no Optimus-specific emissions data, so a measured emission profile for the robot is an honest absence, not a known quantity.

### Is a Tesla Optimus safe to be around in terms of emissions?

On the regulatory floor, an Optimus sold in the US would have to meet the FCC's Part 15 emission limits like any consumer electronic, which is the same standard your existing devices meet. That is meaningful, but it is a baseline every gadget clears, not an Optimus safety certificate, and Tesla has published no measured emission data of its own. We treat the federal limit as the applicable framework and the Optimus figures as absent.

### Would a Tesla Optimus be noisy in a quiet home?

Probably noticeable but not disruptive, by analogy to appliances, though it is undisclosed. A machine with electric actuators would plausibly sit in the dishwasher-to-vacuum range, loud enough to hear moving through a room but not like a power tool. That is an honest inference from comparable machines. Tesla has stated no actual figure, so the real loudness is an honest absence.
