How many watts is loud for a car speaker?

Car speakers over 110 decibels per watt are too much. Besides the car speaker, any sound amplification devices for entertainment have a range that a human ear can handle.

First, you need to know how much a human ear can handle. As for the research that goes on the human ear, an ordinary human ear can stand up to 85 decibels per day on average.

However, if the sound extends to 120 decibels, it can cause immediate eardrum injury. Therefore, when it comes to car speakers, a sound level over 110 decibels is kind of useless.

Therefore, loudness over 110 decibels is too much for a car speaker. However, a car has several types of speakers, such as horns, music, smart assistant, external speakers, etc.

Different speakers in a car serve different purposes. However, all speakers have a maximum output range of 110 decibels because sound pollution is a big issue in the modern world.

Do all cars need external speakers?

The answer is no. Not all cars have external speakers. It depends on several factors if a car needs an outside speaker or not.

Let’s talk about it here.

Generally, an internal combustion engine car does not need an external speaker. Now, you may ask where the horn’s sound comes from. Well, speakers do not produce typical horn sounds.

A device named a horn is under the hood of the car. It is connected to the car’s battery, and the horn’s circuit completes when you press the switch under the steering wheel cover.

When you press the switch, the electrical signal flows through the circuit. The horn converts the electrical signal to audible noise that you hear.

However, what about electric cars? Electric cars run silently, which is a critical issue. Many passersby estimate crossing the road by hearing vehicles’ noise. By noise, I mean the sound from the engine.

But for electric cars, there is no noise. Thus, some companies, such as Tesla, started using external speakers. External speakers mimic the internal combustion engine’s sound.

In other words, as electric and hybrid car users are increasing exponentially, external speakers are becoming more important.

Can car speakers damage ears?

Yes, a car speaker can damage your ears at any point. However, it does not occur very often.

Car speakers can raise their loudness to 120 decibels depending on what music you are playing. And 120 decibels is bad news. It can damage your ears’ structure of hair cells. As a result, you will lose your hearing.

But again, it does not occur often, as most car speakers nowadays come with smart controls. Thus, if your song’s decibels go higher than the comfort limit, it will notify you, or it will reduce the sound volume automatically.
