I want to use in back yard to measure highway sound levels. Will this instrument do that with reasonable accuracy?

I would say it is fairly accurate. I compared it to my more expensive Radio Shack and the numbers are very comparable.

I have only used this unit briefly for measuring speaker levels. I would imagine it could work for highway noise levels as well.

Really, Rebecca, I wouldn't suggest purchasing this. We had our first one, and the display stopped working very early on, so I thought maybe the battery was bad. When I went to try to change it, there was a mini spark or something shorted. I called the company and sent it in after which they did replace it at no charge. However, we never found it precise in terms of being able to determine sound levels. We used it for voice, and it just went all over the place with no ability to control it in any way. Sorry to sound so negative, but that's what happened to us. I think it would probably measure levels but not with any great precision. Really, Rebecca, I wouldn't suggest purchasing this.

I think so. It jumps around as the noise level changes but then gives high low and average

I think that this unit should be of use. The digital display will fluctuate, however note that there is one extra button on the side which when pressed will show the highest and the lowest db recorded on last recording.

I don't know they shipped it i payed for it never showed up crappy service buy something different

You can but keep in mind the accuracy is not survey quality. Best accuracy I've seen with it is +/- 10 feet.

The device is absolutely sensitive enough that you would be able to see even relatively small changes in sound levels. (For example, in a quiet room, I can actually see this device detecting a loudly ticking clock or the sounds of residential traffic at least 150 yards away reaching the inside of my home with my windows closed.) However, this sensitivity may also be a problem for you. When you first turn the device on you will see a spike in the reading for a few seconds until the device "normalizes" to the environment you are using it in. While you will be able to determine that overall the sound levels have changed during a commercial, those sounds levels are not constant, that is, you may also see wide fluctuations as each word is spoken or as music is played. Sound levels change constantly in a normal household environment with each spoken word, each movement of the device, traffic outside the home, other sounds turning on/off (e.g., heating systems), a dog barking two houses away, etc. So while the device is sensitive enough to detect an overall level change, I think the sensitivity could also be a problem if you do not consider EVERYTHING causing changes in the readings. Hope this answers your question !!!

Yes, That is what I used mine for. I measured it by car and mine goes for about 1/2 mile. Make sure to turn the volume up pretty high on your music source.

if there is an item ( my case a deer or a target ) it is very accurate but a friend was looking for a distance to a spot in a field and it had nothing to bounce the signal off so it wouldn't work. the item has to be vertical and substancial.

Depending on the distance, it will be less accurate the farther away you get. It should give a decent approximation at that distance.

I don't understand the question, but regarding accuracy of readings, I have no other calibrated instrument with which to check the accuracy of the readings displayed with this product. Generally, they appear to be reasonable based on published noise decibel readings.

This isn't the tool you want for just measuring volume. Get a Radio Shack Db meter for that.

It's 150 max but dependant on the area you intended to push sounds to 50 per side would probably do ok. That said Pyle makes a good amp/receiver for about $150. That has got cops our to my house twice ..and we don't have noise ordenence laws.

We have tested this radio, line of sight, out to 7 miles. I'd say it would work well for this application. I would suggest a throat mike for bar security. The ear peice would be valuable

That's hard to say, too many acoustic variables to consider, outside noise, conversations, etc...If the setting was relatively quiet, it may do the job. I use mine at work in a factory, and it really carries the sound when there is not a lot of secondary noise going on.

It would register the sound level, you would have to determine in advance what level would be too loud. OSHA for example states that 85 db (time weighted average) is too loud therefore hearing protection is required. You might state that peaks of sound above 90 db would be your "too loud" point. The meter will register the noise accurately.

I use it every Friday night to measure the sound levels of our bands. I use it maybe 6 or 7 times a night just once a week. It works fine for what I need it for...Have had it about 5 months, so have maybe turned it off an on 100 times total, but I don't leave it on. I just take a reading and then turn it off...Hope this helps...

I live in a more rural setting. Not sure how much leeway you have with your back yard situation, but it is loud enough to be heard and identified by neighbors. Not sure which, among the others you mention, is more quiet.

Probably not loud enough for your needs. It works good for outside patio area with little back ground noise.

I don't know why not, I just measured the sound of an air compressor in a closed garage today, works great!

This device should be able to measure anything in the human hearing range. Note that some ultra- and sub-sonic frequencies can affect humans, but are not directly "audible".
