Overview

This model, the NMAPI-SE, is the most popular of the NoiseAPI range. Designed to be wall mounted indoors or outdoors it is protected against poor weather conditions and high dust levels. Even where environmental conditions are good we recommend this model as it is easier to install and provides excellent protection against damage.

NoiseAPI

The NoiseAPI devices incorporate a microphone and precision noise processor, which carries out all the acoustic sampling and calculations that are involved in sound level measurement. The results are presented to your application by a well documented Application Programming Interface (API), so you can concentrate on displaying the results and generating noise reports.

The NoiseAPI responds to HTTP or HTTPS requests, either sent directly to it over your local network or through our optional routing server. There is also a WebSocket interface that you can use if you want a live feed of the sound levels or noise event notifications.

How It Works

The NoiseAPI device needs power - a power adapter is included - and a network connection. It connects to your local network with a CAT5 Ethernet cable or by WiFi. Your software can now communicate with the NoiseAPI on your local network using HTTP requests.

Free Evaluation Account

Full API documentation, along with code samples and live examples are available through an account on our NoiseAPI server. Using an evaluation account, you can also communicate with a NoiseAPI device via our routing server. This is useful to ensure your code can communicate with it successfully and to check that the results are exactly what you need.

Please email NoiseMeters with a few details about your application and requirements. We will email back with login details for an evaluation account that you can use to see if NoiseAPI is the right solution for your application.

HTTP / HTTPS Requests

Most commands are available as HTTP or HTTPS GET requests. The noise measurements available are:

Time History Noise Profile

  • Measurements every second
  • Parameters include LAeq (average sound level), Lmax, Lmin

Periodic Noise Measurements

  • Typically used for environmental noise monitoring
  • User selectable periods, typically 15 minutes or 1 hour
  • Parameters include LAeq, Max, Min and Ln (e.g. L10, L90, user selectable)

Noise Events

  • Detect high noise levels
  • Template of sound levels and durations
  • Parameters include event duration (seconds), LAeq, Max, Min, level every second during event

Responses

All responses to commands and downloads are formatted as JSON.

For example, a request for 10 seconds of time history measurements would give:


{
"cmd": "timehistory",
"status": "ok",
"from": "2021-02-16T06:00:00.000Z",
"to": "2021-02-16T06:00:09.000Z",
"laeq": [43,43,43.1,43.1,43.1,43.1,42.9,42.9,43,42.9]
}

WebSockets

If you want a live feed of sound levels or alerts when noise events occur you can use a WebSocket connection to the NoiseAPI device. You can mix HTTP and WebSocket connections on the same NoiseAPI device.

Full Documentation

Full documentation, code samples and connections to NoiseAPI devices are available from your account on noiseapi.com. Please contact us for a free evaluation account.

Networking

The NoiseAPI device connects to your network using a Ethernet cable (Cat 5e, RJ45) or WiFi. While the NoiseAPI benefits from connection to the Internet (clock sync and access via our routing server), it can be used in a totally isolated setup.

Outdoor Installations

The NMAPI-SE model has an Ethernet connection (RJ54) for connection to your wired network. This is a weatherproof socket and for outdoor use you will need a suitable weatherproof cable or weatherproof RJ45 cable housing. For indoor use a standard Cat 5e network cable can be used.

Routing Server

For a standard installation you will be able to access the NoiseAPI from other computers on your network. With some routing in place you could access it from anywhere on the Internet. In this case you do not need the Routing Server option.

Rather than getting involved in network routing you can make use of our Routing Server. In this case the NoiseAPI device connects to our server and you send your API requests to noiseapi.com instead of directly, so you can communicate from anywhere in the world.

There is an annual charge for use of the routing server.

Installation

mounting the noiseapi

The NoiseAPI can be installed inside or outside, mounted on a wall. It mounts with four screws that can be accessed from the front of the box with front panel removed.

Power

The NMAPI-SE model comes with a 10m (32 ft) power cable fitted through a weatherproof gland. This cable can be shortened if necessary. A 24V DC power adapter is included. The power adapter must be mounted indoors or in a suitable enclosure as it is not weatherproof.

Ethernet Cable

If mounting outside and using an Ethernet cable for networking, you will need a weatherproof Ethernet cable or a weatherproof RJ45 cable adapter.
