How to show a notification without a sound java

Question

How can I make a notification that doesn\'t make a sound when I build it? I am building a notification, and my users don\'t like the fact that it makes a sound.

You can set more than one channel. In my case, my aplication has a background service with two sounds notifications, and one notification without sound. I get it with this code:

//creating channels:

    NotificationChannel channel1 = new NotificationChannel(CHANNEL_ID_1, "CarNotification1", NotificationManager.IMPORTANCE_HIGH);
    NotificationChannel channel2 = new NotificationChannel(CHANNEL_ID_2, "CarNotification2", NotificationManager.IMPORTANCE_MIN);
    NotificationChannel channel3 = new NotificationChannel(CHANNEL_ID_3, "CarNotification3", NotificationManager.IMPORTANCE_HIGH);

    //mSound1 and mSound2 are Uri
    channel1.setSound(mSound1, null);
    channel3.setSound(mSound2, null);

and when I create the notification:

String channelId;
switch (situation){
    case situation2:
        channelId=CHANNEL_ID_2;
        break;
    case situation1:
        channelId=CHANNEL_ID_1;
        break;
    default:
        channelId=CHANNEL_ID_3;
}

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId);
//etcetera
