当MySQL中的新记录 - HTML表格时发出哔声

Question

So, I have a PHP - Symfony 3 project connected to a MySQL Database through an API to let customers place orders through an Android APP. I need the Browser to play a beep sound when a new order has been placed (orders are shown in an HTML table) So I guess the sound has to be played using Javascript when the table changes. Any ideas on how to accomplish this? Thank you in advance. I will post the index view code below if it helps

{% extends 'base.html.twig' %}

{% block body %}
<h1 class="page-header">Listado de Aderezos</h1>

<table class="table table-striped table-responsive" id="data">
    <thead>
        <tr>
            <th>Id</th>
            <th>Nombre</th>
            <th>Descripcion</th>
            <th style="display:none;">Deleteat</th>
            <th>Acciones</th>
        </tr>
    </thead>
    <tbody>
    {% set cont = 0 %}
    {% for Aderezo in aderezos %}
        <tr>
            <td><a href="{{ path('aderezo_show', { 'id': Aderezo.id }) }}">{{ Aderezo.id }}</a></td>
            <td>{{ Aderezo.nombre }}</td>
            <td>{{ Aderezo.descripcion }}</td>
            <td>{{ Aderezo.deleteAt }}</td>
            <td>
                <div class="btn-group">

                            <a id="viewedit{{ cont }}" class="btn btn-sm btn-outline-primary" href="{{ path('aderezo_show', { 'id': Aderezo.id }) }}">show</a>
                            {% set cont = cont + 1 %}

                            <a id="viewedit{{ cont }}" class="btn btn-sm btn-outline-primary" href="{{ path('aderezo_edit', { 'id': Aderezo.id }) }}">edit</a>
                            {% set cont = cont + 1 %}
                                <a class="btn btn-sm btn-outline-danger" href="{{ path('aderezo_delete', { 'id': Aderezo.id }) }}">Eliminar</a>                    </div>

If it's a simple sound you can base64 encode the binary data of the file into a string. See this answer.

Then play the sound through Javascript. See this answer.
