I want to move by analyzing the ambient sound of this indicator
What code do I need in the block?
Using the same method that I used for showing the light meter in your other topic, how to display the sound level:
<!DOCTYPE html>
<html>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
<head>
<title>BarSound</title>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
</head>
<body>
<div id="chart_div"></div>
<script>
google.charts.load('current', {packages: ['corechart', 'bar']});
google.charts.setOnLoadCallback(drawMultSeries);
function drawMultSeries() {
var data = google.visualization.arrayToDataTable(
//replace this section with your list and live value
[ ['Sound', 'Level'], ['Sound', 800] ]
// live value here = 800
);
var options = {
title: 'Sound Analysis',
legend: {position: 'none'},
chartArea: {width: '90%'},
hAxis: {
title: 'Sound Level',
viewWindow:{
max:1000,
min:0
}
},
};
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</body>
</html>

How should I put this code in the block?
Any way I do it is not right 
What does not work, simply no chart shows up, at all?
Not just a blank page
<!DOCTYPE html>

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">

<title>BarSound</title>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
</head>
<body>
<div id="chart_div"></div>
<script>
google.charts.load('current', {packages: ['corechart', 'bar']});
google.charts.setOnLoadCallback(drawMultSeries);
function drawMultSeries() {
var data = google.visualization.arrayToDataTable(
soundList
);
var options = {
title: 'Sound Analysis',
legend: {position: 'none'},
chartArea: {width: '90%'},
hAxis: {
title: 'Sound Level',
viewWindow:{
max:1000,
min:0
}
},
};
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, options);
}

You should also check the values coming back as decibels, they may be quite small, using a different scale to 0 - 1000....
Now he came
But I think it is not connected to the voice recognition sensor because it does not increase the sound of its effective environment
noone?
duplicate topic ...moving
I understood to mean that the graph was now working?
Did you check the values being returned by the sound analyser ?
No not working
In a fixed value
Remaining constant value
I want to adjust the ambient sound
I realise that, I simply wanted to check if the basic setup worked.
Yes, it worked
